TS924IN - Quad 4MHz Rail-to-Rail Op Amp | STMicroelectronics

STMicroelectronics TS924IN is a quad, rail-to-rail BiCMOS operational amplifier optimized for 3 V and 5 V operation, with four amplifier channels, 4 MHz gain-bandwidth product, 1.3 V/us slew rate, and low input-offset voltage up to 900 uV. The device is supplied in a 14-pin DIP package, making it suitable for conventional through-hole and legacy industrial designs. An operational amplifier is a high-gain analog signal-conditioning IC used in the broader voltage-amplifier and analog IC hierarchy. The TS924IN combines four independent amplifiers in one package, allowing compact implementation of filters, amplifiers, comparators, instrumentation circuits, and signal-conditioning stages. Its rail-to-rail output design supports operation close to the supply rails, while its BiCMOS construction combines bipolar input characteristics with CMOS output stages. The headline specifications are 4 MHz gain-bandwidth product, 1.3 V/us slew rate, and input offset voltage of 900 uV maximum. The TS924 family is fully specified for 3 V and 5 V supply operation, and the supplied operating-range information extends to 12 V. Its high output-current capability is particularly useful for driving low-impedance loads compared with many general-purpose op-amplifier choices. Each channel can operate as an amplifier, comparator, or active-filter building block. The wide available bandwidth supports signal paths that need more gain-bandwidth than low-speed precision-oriented amplifiers, while the 1.3 V/us slew rate allows moderate-amplitude signals to transition without excessive distortion. Four integrated channels can reduce package count and simplify board layout in multi-channel measurement and control systems. Typical uses include industrial sensor interfaces, low-voltage audio and communication circuits, active filters, data-acquisition front ends, process-control loops, and general-purpose analog signal conditioning. The 14-DIP format is especially useful when maintaining an existing through-hole design or avoiding a conversion to a surface-mount footprint. Input and output protection should still be considered because the verified data does not establish the maximum input or output voltage range. The principal design consideration is the power relationship between supply voltage, output swing, load current, and dissipation. Because no thermal-resistance or absolute maximum-rating data was included in the verified results, those values must be confirmed in the manufacturer datasheet before production release. Decoupling capacitors should be placed close to the supply pins and return pins should follow a low-impedance layout. This product record combines verified manufacturer and distributor information, package-specific replacement guidance, practical design considerations, and a parameter comparison that helps engineers distinguish true pin-compatible alternatives from merely functional substitutes. It supports component selection for legacy 14-DIP analog designs without treating incompatible package or performance variants as drop-in replacements.

TS925ID

TS925ID - Quad 4MHz Rail-to-Rail Op Amp | STMicroelectronics

STMicroelectronics TS925ID is a quad operational amplifier with rail-to-rail input and output capability, 4 MHz gain-bandwidth product, 1.3 V/us slew rate, and operation from 2.7 V to 12 V in a 16-pin SOIC package. Each amplifier can deliver 80 mA of output current, allowing it to drive up to 32 loads according to the manufacturer documentation. An operational amplifier is an analog signal-processing IC that uses high open-loop gain to amplify voltage differences between two inputs. The TS925ID belongs to the operational-amplifier hierarchy and combines four amplifiers in one package. Rail-to-rail input behavior supports operation near the positive and negative supply rails, while rail-to-rail output behavior provides greater output-voltage range than conventional amplifiers constrained by the supply rails. The principal features include 9 nV/Hz input-voltage noise, low distortion, 4 MHz bandwidth, and 1.3 V/us slew rate. The 80 mA output-current capability distinguishes the TS925ID from lower-current general-purpose op amps, making it useful where several amplifiers must drive heavier resistive or capacitive loads. Its quad configuration also reduces board area by integrating four amplifier channels. The TS925ID combines bipolar input and CMOS output stages, identified in technical listings as a BiCMOS amplifier. This architecture supports rail-to-rail operation while retaining low-noise bipolar input characteristics. Because the four channels share a common package, careful consideration of power-supply routing, grounding, output isolation, and thermal behavior is required in multi-channel analog systems. Typical uses include audio output stages, active filters, sensor-conditioning circuits, buffer amplifiers, communications receivers, and industrial control systems. Its quad organization is particularly useful when a design needs four closely related analog channels. The adjustable phantom-ground feature can support signal references in applications requiring an artificial ground, while the standby mode can reduce power consumption when the amplifier is not needed. Designers should use the manufacturer datasheet to verify the complete electrical limits, pin configuration, output-current conditions, stability requirements, and recommended external components. Decoupling capacitors should be placed close to the supply pins, and outputs that drive capacitive loads may require isolation resistors or other stability measures. Because the available verified specification excerpt does not provide the complete pin table, the package diagram should not be used as a substitute for the official datasheet. This page consolidates the verified TS925ID operating range, bandwidth, slew rate, noise, output-current, package, pricing, and sourcing information into an engineering-focused reference. It also distinguishes verified same-package alternatives from parts that require package or electrical revalidation, helping designers make a safer replacement decision before committing a new PCB layout.

TS931BILT

TS931BILT - 100kHz Rail-to-Rail Micropower Op Amp | STMicroelectronics

The STMicroelectronics TS931BILT is a single-channel CMOS operational amplifier in a SOT-23-5 package, featuring rail-to-rail output swing, micropower consumption, and operation down to 2.7 V single supply. As a member of the TS93x family (single/dual/quad variants), it delivers 100 kHz gain-bandwidth product while drawing only a few microamps of quiescent current, making it an excellent choice for battery-powered and portable applications. An operational amplifier (op-amp) is a high-gain DC-coupled electronic voltage amplifier with differential inputs and, typically, a single-ended output. Within the broader signal-conditioning hierarchy, op-amps sit between transducers/ADC front ends and downstream digital processing; rail-to-rail output variants extend the usable output swing to nearly both supply rails, maximizing dynamic range in low-voltage systems. Micropower CMOS op-amps like the TS931BILT optimize this topology for low-Iq operation, trading GBW and slew rate for extended battery life in handheld, IoT, and remote-sensor designs. Key specifications include a 2.7 V to 10 V supply range, 100 kHz GBW, rail-to-rail output (reaching 2.9 Vpp with RL = 100 kΩ at 3 V supply), CMOS input stage, and an operating temperature range of -40 °C to +105 °C. The SOT-23-5 package is among the smallest standard op-amp footprints, enabling compact PCB layouts in space-constrained designs. Architecturally, the TS931BILT uses a CMOS input stage with a class-AB output stage to deliver rail-to-rail output swing at low quiescent current. The 'B' suffix denotes the enhanced second-generation variant, offering improved offset and noise compared with the original TS931, while the 'I' in 'ILT' indicates the industrial temperature grade (-40 °C to +105 °C). Typical applications include battery-powered instrumentation, portable medical devices, sensor signal conditioning, active filters, and transducer interfaces. The micropower Iq makes it ideal for always-on circuits where sleep current must be minimized. When designing with this op-amp, note that the CMOS inputs have lower bias current than bipolar alternatives but may exhibit higher leakage at elevated temperatures. Decouple the supply with a 100 nF ceramic capacitor placed close to the VCC pin to suppress noise. This page synthesizes distributor pricing, drop-in alternatives within the same SOT-23-5 footprint, and practical design notes that go beyond the manufacturer datasheet, helping engineers select the right op-amp quickly.

TS931ID - 100kHz Rail-to-Rail Op Amp | STMicroelectronics
TS931ID

TS931ID - 100kHz Rail-to-Rail Op Amp | STMicroelectronics

The STMicroelectronics TS931ID is a single-amplifier, general-purpose operational amplifier with a 100 kHz gain-bandwidth product, rail-to-rail output operation, and a 2.7 V minimum supply voltage, packaged in an 8-pin SOIC. It operates from single 2.7 V to 10 V supplies, consumes approximately 20 µA, and provides an extremely low typical input bias current of 1 pA. The device is suited to portable instrumentation, low-power signal conditioning, buffering, and general analog signal-processing applications. An operational amplifier, or op amp, is an analog integrated circuit that provides high open-loop gain and feedback control for amplification, filtering, comparison, buffering, and signal conversion. The TS93x family belongs to the broader operational-amplifier hierarchy, which includes instrumentation, rail-to-rail, micropower, and precision amplifier categories. Rail-to-rail output operation allows the TS931ID to approach its supply-voltage limits at the output, improving dynamic range in low-voltage systems where usable signal headroom is limited. The TS931ID provides several characteristics suited to compact analog designs. Its 100 kHz gain-bandwidth product supports moderate-frequency amplification and feedback networks, while the approximately 20 µA supply consumption suits battery-operated equipment. The 1 pA typical input bias current minimizes disturbance to high-impedance sources. According to the available STMicroelectronics datasheet material, the device can reach a 2.9 Vpp output swing with a 100 kΩ load when supplied at 3 V. The TS931ID uses CMOS inputs and includes ESD protection, making it appropriate for low-leakage analog interfaces. Rail-to-rail output swing improves usable signal range near the positive or negative supply rail, but input common-mode behavior, output-current capability, stability, and drive into capacitive loads must still be checked against the complete operating condition. The single-amplifier configuration also reduces board area when one independent analog channel is required rather than a dual or quad device. Typical uses include low-power sensor conditioning, portable measurement systems, analog buffering, low-current-to-voltage conversion stages, and small-signal control circuits. Its combination of a 2.7 V minimum supply, 20 µA-class consumption, and 100 kHz bandwidth is particularly relevant to battery-powered instrumentation. The 8-pin SOIC package supports conventional surface-mount assembly and is convenient for prototypes, repair, and mixed analog or mixed-signal boards. Designers should account for output headroom when driving loads, verify stability with the selected feedback network and load capacitance, and route sensitive input traces away from switching nodes. Input and output bypassing must follow the manufacturer recommendations. Because the verified source set does not provide complete offset, slew-rate, common-mode-range, and absolute-maximum-rating tables, those values should be confirmed in the official datasheet before a safety- or precision-critical design is released. This page consolidates the verified distributor specifications, package information, purchasing reference, family-level alternatives, and practical analog-design guidance. It also distinguishes documented values from parameters that still require direct confirmation from the manufacturer datasheet, helping engineers move from part selection to PCB implementation without presenting unverified figures as facts.

TS932ID

TS932ID - Dual 100 kHz Rail-to-Rail Op Amp | STMicroelectronics

The STMicroelectronics TS932ID is a dual, rail-to-rail-output micropower operational amplifier with a 100 kHz gain-bandwidth product, 0.05 V/µs slew rate, and a 2.7 V to 10 V supply-voltage range. The device is supplied in an 8-pin SOIC package and is intended for low-power, low-frequency signal conditioning where low supply current and CMOS input characteristics are important. An operational amplifier, or op amp, is a high-gain analog building block used to amplify, buffer, compare, and filter signals. The TS93x family belongs to the amplifier IC hierarchy, where rail-to-rail output stages allow an output voltage to approach the supply rails. This capability makes the TS932ID suitable for battery-powered sensors, portable instrumentation, and low-voltage analog interfaces. Key characteristics include a 100 kHz gain-bandwidth product, 0.05 V/µs slew rate, and typical supply-current consumption of 20 µA. The output can reach 2.9 Vpp when supplied from 3 V with a 100 kΩ load. The TS93x series also features CMOS inputs, ultra-low input bias current of approximately 1 pA, and ESD protection. These characteristics favor high-impedance sources and energy-limited systems rather than demanding high-speed or high-precision instrumentation. The TS932ID is a dual amplifier, allowing two independent signal paths in one package. Its rail-to-rail output architecture simplifies signal conditioning near low supply voltages, while its micropower operation reduces the burden on batteries or harvested-energy supplies. The 100 kHz bandwidth is adequate for audio-frequency, sensing, and general-purpose feedback-control loops, but it is not intended for high-frequency filtering, video amplification, or communications waveform processing. Typical applications include battery-operated sensor conditioning, low-current comparator or threshold functions, portable measurement modules, low-frequency active filters, analog sensor interfaces, and general-purpose buffering. In each case, the device provides two amplifier channels in a compact 8-pin SOIC while consuming approximately 20 µA under the stated family conditions. Designers should verify output load, input common-mode range, output swing, noise, offset, stability, and operating-temperature limits against the manufacturer datasheet before release. Decoupling capacitors should be placed close to the supply pins, and feedback-network components should be selected with practical bias-current and leakage considerations. This page consolidates the verified distributor information, manufacturer-family characteristics, package details, application guidance, and substitution limitations for TS932ID. It also distinguishes documented drop-in options from unsupported cross-package or functional substitutes so engineers can make a traceable replacement decision.

TS934ID - 4-Channel 2.7V R-R Micropower Op Amp | STMicroelectronics
TS934ID

TS934ID - 4-Channel 2.7V R-R Micropower Op Amp | STMicroelectronics

The STMicroelectronics TS934ID is a quad, rail-to-rail output, micropower operational amplifier designed for low-voltage signal conditioning and battery-powered systems. It contains four amplifiers in a 14-pin SOIC package, operates from 2.7V to 10V, supports single-supply operation, and is specified for a 100kHz gain-bandwidth product. The device combines a typical 20uA supply current with CMOS inputs, ultra-low input bias current of 1pA, and rail-to-rail output voltage swing. According to the manufacturer datasheet family information, the TS93x series is intended for portable instrumentation, sensor interfaces, and general-purpose analog signal processing. An operational amplifier is an analog integrated circuit that amplifies the voltage difference between its differential inputs while providing high input impedance and low output impedance. The TS934ID belongs to the operational-amplifier hierarchy, which includes general-purpose amplifier ICs, micropower amplifiers, rail-to-rail amplifiers, and CMOS-input analog ICs. Its four integrated channels reduce the number of packages required when several low-frequency signals must be conditioned in the same system. The principal features are the 2.7V minimum supply voltage, 10V maximum supply voltage, 100kHz bandwidth, 0.05V/us slew rate, and approximately 20uA typical supply consumption described for the TS93x family. The output stage can reach 2.9Vpp with a 100kohm load when supplied from 3V, making the amplifier suitable for modest-swing signals in low-voltage systems. CMOS inputs minimize input bias current, which is advantageous when the source impedance is high. The TS934ID is not intended as a high-speed, high-voltage, or precision replacement for every general-purpose quad amplifier. Its 100kHz bandwidth and micropower bias favor portable and instrumentation applications over wideband signal chains. Designers should verify output swing, common-mode range, noise, offset, stability, and load capability against the complete manufacturer datasheet before using it with unusual source impedances, capacitive loads, or rail-to-rail input signals. Typical uses include battery-powered sensor conditioning, portable measurement equipment, industrial transducers, audio and communications interface circuits, and general 3V instrumentation. The 14-SOIC package is suitable for conventional through-hole PCB assembly and automated manufacturing. Because the device is a four-channel amplifier, one package can serve multiple independent amplifier sections in a compact analog front end. A key design consideration is power budgeting. The low supply current supports battery-operated systems, but the output still requires a stable supply and suitable bypass capacitance. The amplifier should be operated within the specified supply range and load conditions, and its output should not be used as a power-stage output. Pin assignments, common-mode behavior, and package details should be taken directly from the STMicroelectronics datasheet and pinout diagram. This page combines verified distributor and manufacturer-linked information, drop-in comparison candidates, pricing fields, application guidance, and practical design notes to support faster component selection and PCB planning.

TS941ID - 2.5-10V Rail-to-Rail Op Amp | STMicroelectronics
TS941ID

TS941ID - 2.5-10V Rail-to-Rail Op Amp | STMicroelectronics

STMicroelectronics TS941ID is a single-circuit, general-purpose operational amplifier featuring a rail-to-rail output, 2.5 V to 10 V supply operation, and an 8-pin SOIC package. The device belongs to the TS94x micropower operational-amplifier family and is designed for instrumentation, signal buffering, and other low-voltage analog signal-chain applications. Its low-noise operation, high input impedance, and approximately 1 pA input-bias current support accurate handling of high-impedance sources while its rail-to-rail output improves dynamic range near the positive and negative supply rails. An operational amplifier, or op amp, is a high-gain differential amplifier used to amplify, buffer, compare, and filter analog signals. The TS941ID sits within the operational-amplifier hierarchy and operates from a 2.5 V to 10 V supply, making it suitable for battery-powered, industrial-control, test-and-measurement, and portable equipment. Its rail-to-rail output stage allows the output voltage to approach the supply limits more closely than a conventional output stage, although the exact output swing and input common-mode behavior must be checked in the manufacturer datasheet for the selected supply voltage. Key features include a single amplifier configuration, rail-to-rail output, low-noise operation, high input impedance, and very low input-bias current of approximately 1 pA. The 2.5 V minimum supply voltage supports compact, low-energy systems, while the 10 V maximum provides compatibility with common industrial and laboratory supply rails. The manufacturer specifies operation over -40 °C to +85 °C, covering industrial temperature requirements without requiring an automotive-qualified variant. The TS941ID is intended for general-purpose precision signal conditioning rather than as a high-speed communications amplifier. Its micropower-oriented design is valuable when battery current is important, but the precise quiescent-current value should be taken from the manufacturer datasheet. The approximately 1 pA input-bias current is particularly useful with high-impedance sensors because it limits the DC current drawn through the source resistance and helps reduce input-offset errors. Typical applications include sensor-signal conditioning, low-current transimpedance buffering, portable instrumentation, industrial measurement, and general analog signal conditioning. In a transimpedance stage, the TS941ID can be paired with a suitable feedback resistor and compensation capacitor while its low input-bias current reduces bias-current-induced error. In instrumentation, it can buffer inputs before a higher-precision converter or provide gain around sensors whose output range does not use the complete supply span. When designing around the TS941ID, verify input common-mode range, output swing, unity-gain stability, noise, slew rate, and quiescent current against the actual load and supply conditions. Place input, feedback, and decoupling connections for low noise and stable feedback operation, and include adequate output-current margin for capacitive or resistive loads. The 8-pin SOIC footprint is convenient for conventional surface-mount assembly but is not as compact as the smallest QFN packages. This product page consolidates the verified manufacturer information, distributor availability references, family-level alternatives, parameter comparisons, and practical design guidance. It distinguishes confirmed TS941ID data from specifications that still require confirmation from the manufacturer datasheet, helping engineers identify the part faster without presenting unverified values as established facts.

TS944IPT - Quad Rail-to-Rail 1.2µA Op-Amp | STMicroelectronics
TS944IPT

TS944IPT - Quad Rail-to-Rail 1.2µA Op-Amp | STMicroelectronics

The STMicroelectronics TS944IPT is a quad CMOS-input operational amplifier delivering rail-to-rail output swing while consuming only 1.2 µA typical quiescent current per channel, packaged in a 14-pin TSSOP (Tape & Reel). It operates from a single 2.5 V to 10 V supply over the -40 °C to +85 °C industrial temperature range and provides a gain-bandwidth product of 10 kHz, making it ideal for ultra-low-power signal conditioning. An operational amplifier (op-amp) is a high-gain DC-coupled differential amplifier that uses external feedback components to set closed-loop gain, bandwidth, and transfer function. The TS944 belongs to the micropower CMOS op-amp family — a class of linear ICs that prioritize nano- to micro-amp quiescent current draw for battery-powered and energy-harvesting designs. Within the broader semiconductor hierarchy, it sits under: op-amp -> amplifier -> analog IC -> linear IC -> integrated circuit. Key features include four independent op-amp channels in one package, CMOS inputs delivering ultra-low input bias current, rail-to-rail output swing that maximizes dynamic range on low-voltage supplies, and 1.2 µA typical supply current per amplifier that enables years of runtime from small cells. The device is unity-gain stable and supports single-supply operation from 2.5 V to 10 V, simplifying designs that previously needed bipolar ±5 V rails. The TS944 architecture uses a CMOS input stage that achieves very low bias current while the class-AB output stage swings to within millivolts of both supply rails. This combination eliminates the need for input bias-current compensation in high-impedance sensor interfaces and lets designers operate the part directly from a single lithium cell or 3.3 V digital rail without sacrificing headroom. Typical applications include battery-powered sensor signal conditioning, portable medical monitors, IoT edge nodes, active filters, transducer pre-amplifiers, and any micropower analog front end where four amplifiers must fit in a small 14-pin TSSOP footprint. Designers should bypass supplies with 100 nF ceramic capacitors placed within 5 mm of VCC and avoid capacitive loads above 1 nF without an isolation resistor to prevent oscillation.

TS951ID - 3MHz Rail-to-Rail Low-Power Op Amp | STMicroelectronics
TS951ID

TS951ID - 3MHz Rail-to-Rail Low-Power Op Amp | STMicroelectronics

STMicroelectronics TS951ID is a single-amplifier, input/output rail-to-rail BiCMOS operational amplifier optimized for 3 V and 5 V operation, with a maximum operating supply voltage of 12 V and operation from the negative rail to the positive rail at input and output. The device is packaged in an 8-pin SOIC and provides approximately 3 MHz gain-bandwidth product, 1 V/µs slew rate, and 80 dB supply-voltage rejection ratio. Its low-power design targets portable instrumentation, sensor interfaces, audio signal conditioning, and general-purpose analog systems. An operational amplifier is an analog integrated circuit that amplifies the voltage difference between its inverting and non-inverting inputs while offering high input impedance, low output impedance, and stable closed-loop behavior when feedback is applied. The TS951 belongs to the operational-amplifier hierarchy, where its BiCMOS input stage combines bipolar transistor performance with CMOS power efficiency. Rail-to-rail input and output operation extends useful signal range toward the supply rails, making the amplifier practical in low-voltage systems that cannot tolerate substantial headroom loss. Key benefits include 3 MHz gain-bandwidth product for modest-frequency signal paths, 1 V/µs slew rate for faster large-signal transitions, and 80 dB supply rejection for reducing supply ripple that could otherwise modulate the amplified signal. The low-power operating approach is useful in portable equipment where energy efficiency and reduced heat generation are priorities. ESD protection rated at 2 kV adds handling robustness, while the compact SOIC-8 package supports conventional surface-mount assembly. The BiCMOS architecture is appropriate for precision and general-purpose analog blocks where low quiescent consumption and rail-to-rail signal handling are more important than high-speed performance. Because this amplifier is intended for low-power rather than high-bandwidth signal chains, applications normally use moderate feedback resistors, explicit gain-setting resistors, and stable output-loading arrangements. Its broad supply capability also permits operation from 3 V and 5 V rails, although each operating point should be checked against the complete electrical limits in the manufacturer datasheet. Typical applications include low-voltage sensor conditioning, buffered analog measurements, portable audio paths, general-purpose instrumentation, and interface buffering around higher-impedance sensors. It can also support low-frequency control or active-filter stages where the 3 MHz gain-bandwidth product provides useful bandwidth margin. In these systems, TS951ID can reduce the loading imposed on the sensor source while maintaining an output signal referenced to the available supply range. Designers should verify input common-mode range, output swing, output-current capability, noise, and stability at the intended frequency before committing the device to a new layout. Decoupling capacitors should be placed close to the supply pins, and sensitive analog inputs should be routed away from switching nodes and high-current return paths. The input and feedback networks must also avoid excessive source resistance or capacitance that could impair stability. This product data combines the verified STMicroelectronics family description, manufacturer datasheet, and distributor listings with practical guidance for package selection, sourcing, and analog layout. It also distinguishes electrically related family members from true drop-in choices and identifies unavailable pricing and lifecycle information rather than presenting unverified commercial figures.

TS952ID

TS952ID - Dual 3MHz Rail-to-Rail Op Amp | STMicroelectronics

STMicroelectronics TS952ID is a dual, input/output rail-to-rail BiCMOS operational amplifier with a 3 MHz gain-bandwidth product, 1 V/us slew rate, and operation from 2.7 V to 12 V in an 8-pin SOIC package. It is optimized and specified for both 3 V and 5 V supply rails, making it suitable for low-voltage analog systems that require an amplifier to approach its supply limits at the input and output. An operational amplifier, or op amp, is a high-gain analog building block used in amplification, buffering, filtering, sensing, and feedback-control circuits. The TS952 belongs to the rail-to-rail op-amp category within the broader amplifier IC and signal-chain hierarchy. Rail-to-rail input and output behavior allows signals near either supply rail to be processed with less conventional headroom loss than a fixed-input amplifier. The TS952ID provides two amplifier circuits, a 3 MHz bandwidth, and a 1 V/us slew rate. According to the STMicroelectronics TS952 product-page data, the device is optimized for 3 V and 5 V operation. Other identified features include an 80 dB supply-voltage rejection ratio, 2 kV ESD protection, and low-power operation. These characteristics make the part applicable to low-voltage sensor conditioning, portable instrumentation, audio input stages, and general-purpose analog signal processing. The BiCMOS architecture combines bipolar input-stage behavior with CMOS output circuitry and is intended to balance low-voltage operation, amplifier performance, and power efficiency. Because the TS952 is a dual device, two independent amplifier channels can share one package. The 8-pin SOIC outline also supports conventional surface-mount assembly, although final stability, bandwidth, and output-current behavior must be evaluated at the intended supply voltage and load. Typical uses include battery-powered sensor interfaces, buffered analog inputs, portable measurement systems, audio preamplification, and low-voltage control loops. At 3 V, the device is aligned with compact battery-operated systems; at 5 V, it provides additional signal range for industrial and consumer analog circuits. The 3 MHz bandwidth is sufficient for many general-purpose conditioning stages but is not intended for high-speed video or precision wideband instrumentation without further analysis. When designing around the TS952ID, verify input and output common-mode limits, output swing, load capability, noise, offset, and stability for the selected supply voltage. Decoupling capacitors should be placed close to the supply pins, and sensitive input traces should remain short and away from switching nodes. Feedback components should follow the manufacturer recommendations because gain-bandwidth, input capacitance, and capacitive loading can affect closed-loop behavior. This product record combines the verified STMicroelectronics family description, distributor package information, operating range, bandwidth, slew rate, rejection, and ESD information with practical selection guidance. It also distinguishes verified facts from specifications that still require confirmation from the complete manufacturer datasheet, avoiding unsupported claims about electrical limits or replacement parts.

TS954ID - Quad 3MHz R-to-R Op Amp | STMicroelectronics
TS954ID

TS954ID - Quad 3MHz R-to-R Op Amp | STMicroelectronics

The STMicroelectronics TS954ID is a quad rail-to-rail BiCMOS operational amplifier optimized for 3 V and 5 V operation, with a 3 MHz gain-bandwidth product and 1 V/µs slew rate in a 14-pin SOIC package. The four amplifiers support supply voltages from 2.7 V to 12 V and combine low-power operation with low input bias current. An operational amplifier is an analog integrated circuit that amplifies the voltage difference between its non-inverting and inverting inputs. A rail-to-rail output amplifier can approach the supply rails at its output, making it useful when the available signal range is small. The TS954 belongs to the amplifier IC hierarchy, where operational amplifiers are used for signal conditioning, buffering, active filtering, comparisons, and analog sensor interfaces. The TS954 family provides four amplifiers per package, a 3 MHz gain-bandwidth product, and a 1 V/µs slew rate. Its input bias current is 35 nA, while the listed supply current is 950 µA per channel. These characteristics make it suitable for general-purpose signal conditioning operating from 2.7 V to 12 V, including low-voltage analog systems and battery-powered equipment. The device uses a BiCMOS input architecture combining bipolar and CMOS process characteristics. Its rail-to-rail output stage allows useful output swing near the supply limits, while the low 35 nA input bias current reduces current errors when driving high-impedance sources. The 3 MHz bandwidth is adequate for audio-frequency and general instrumentation tasks, whereas applications requiring substantially faster closed-loop settling should use a higher-bandwidth amplifier. Typical uses include low-level sensor amplification, active analog filters, audio signal conditioning, instrumentation, and four-channel buffering. The SOIC-14 package permits conventional surface-mount assembly and provides one amplifier per two package pins. Its quad configuration can also reduce board area compared with four separate single or dual amplifier packages when all four channels are required. Designers should verify the required output swing, load impedance, input common-mode range, noise performance, and stability against the manufacturer datasheet before finalizing a circuit. Decoupling capacitors should be placed close to the supply pins, and unused amplifier inputs should be biased according to the manufacturer recommendations so that input and output stages remain in their intended operating regions. This page consolidates verified manufacturer and distributor information for the TS954ID, including the 3 MHz bandwidth, 1 V/µs slew rate, 2.7 V to 12 V supply range, 14-pin SOIC format, sourcing links, and the engineering trade-offs that distinguish a low-power quad amplifier from faster or more specialized alternatives.

TS971ID

TS971ID - 12MHz Low-Noise Rail-to-Rail Op Amp | STMicroelectronics

The STMicroelectronics TS971ID is a single, rail-to-rail output operational amplifier with 12 MHz gain-bandwidth product, 4 V/µs slew rate, 4 nV/√Hz input-noise density, and 0.003% ultra-low distortion. The device operates from 2.7 V to 10 V and is supplied in an 8-pin SOIC package. Its combination of low noise, high gain bandwidth, rail-to-rail output swing, and wide supply range makes it suitable for portable audio, instrumentation, sensor conditioning, and general-purpose signal-processing circuits. An operational amplifier is an analog integrated circuit that amplifies the difference between two input voltages. The TS971ID belongs to the operational-amplifier hierarchy within analog and mixed-signal ICs. Rail-to-rail output means the output can swing close to either supply rail, improving usable output range in low-voltage systems. The single-amplifier configuration also keeps the package compact for cost-sensitive designs requiring one precision analog channel. The principal performance features include 12 MHz gain bandwidth and a 4 V/µs slew rate, allowing the amplifier to process relatively fast signals without excessive settling limitations. Input-noise density is specified at 4 nV/√Hz, and the listed distortion is 0.003%. According to the STMicroelectronics product family information, TS97x devices can operate with supply voltages as low as ±1.35 V and are intended for portable and battery-powered equipment. The TS971ID combines rail-to-rail output operation with low-noise and low-distortion behavior. ESD protection is listed at 2 kV, while latch-up immunity is identified as Class A. These characteristics are particularly useful when a circuit must preserve small-signal information while operating from a constrained supply. The amplifier's 2.7 V to 10 V operating range supports conventional 3.3 V, 5 V, and up-to-10 V system rails. Typical uses include microphone and line-level audio preamplification, portable measurement equipment, low-level sensor interfaces, active filters, and buffered sensor outputs. In an audio preamplifier, the 4 nV/√Hz noise density helps limit the amplifier's contribution to the system noise floor. In instrumentation, the 12 MHz bandwidth provides useful signal range, while the 0.003% distortion specification supports high-fidelity signal paths. When designing a TS971ID circuit, verify the input and output common-mode limits, operating-voltage range, output-current capability, and stability requirements against the manufacturer datasheet. Place input, output, and compensation-network components close to the device, and use a suitable output-load arrangement. Because the verified search results do not provide a public price or a complete manufacturer pin table, those details are not inferred here.

TS972ID - 12 MHz Dual Rail-to-Rail Low-Noise Op Amp | STMicroelectronics
TS972ID

TS972ID - 12 MHz Dual Rail-to-Rail Low-Noise Op Amp | STMicroelectronics

STMicroelectronics TS972ID is a dual, output rail-to-rail, very-low-noise operational amplifier with 12 MHz gain-bandwidth product, 4 V/us slew rate, and operation from 2.7 V to 10 V in an 8-pin SOIC package. Its principal characteristics are 4 nV/Hz noise density, 0.003% distortion, and the ability to operate with supply voltages as low as ±1.35 V. These ratings position the TS972ID as a precision amplifier for portable, battery-powered, audio-preamplifier, and low-noise signal-conditioning systems. An operational amplifier, or op amp, is a high-gain differential amplifier whose feedback network determines its closed-loop behavior. Within the integrated-circuit hierarchy, the TS972ID belongs to the operational-amplifier class, amplifier IC category, and broader analog and mixed-signal semiconductor family. Rail-to-rail output capability lets its output approach the supply rails more closely than a conventional amplifier, improving usable output swing in compact low-voltage systems. The TS972ID combines three defining benefits: 12 MHz gain-bandwidth product for moderate-frequency amplification, 4 V/us slew rate for faster signal transitions, and 4 nV/Hz input-voltage noise for low-noise operation. A 0.003% distortion figure further supports high-fidelity signal paths. The dual configuration provides two amplifiers in one 8-pin SOIC, reducing board area compared with two separate single-channel packages. Its low-voltage operating range and rail-to-rail output architecture suit systems that cannot tolerate the headroom required by conventional amplifiers. The 2.7 V to 10 V supply specification permits operation from a single 3.3 V rail, dual ±2.5 V rails, or other compatible supplies. The manufacturer description specifically identifies portable and battery-powered equipment as suitable markets, while the noise and distortion specifications make audio preamplification a natural fit. Typical uses include portable audio preamplifiers, low-noise sensor conditioning, microphone stages, active filters, and buffered sensor outputs. Two amplifiers in one package can implement dual signal channels, instrumentation front ends, or complementary gain stages when their independent inputs and outputs are required. Care is still necessary when driving capacitive loads, observing output-current limits, and controlling stability around the amplifier and feedback network. The primary design consideration is stable implementation of the intended gain. Input and feedback resistances should be selected consistently with the 12 MHz bandwidth and noise target, while board layout should minimize parasitic capacitance and feedback-loop coupling. Decoupling capacitors should be placed close to the supply pins, and unused amplifier channels should be configured according to the manufacturer guidance rather than left floating. This page consolidates the verified TS972ID operating limits, source references, and same-family alternatives with practical selection and layout guidance. It distinguishes documented facts from parameters requiring confirmation, making the result more useful for PCB compatibility reviews, sourcing, and amplifier design decisions.

TS974ID - 12 MHz Low-Noise Rail-to-Rail Op Amp | STMicroelectronics
TS974ID

TS974ID - 12 MHz Low-Noise Rail-to-Rail Op Amp | STMicroelectronics

The STMicroelectronics TS974ID is a quad operational amplifier with four rail-to-rail output stages, 12 MHz gain-bandwidth product, 4 V/µs slew rate, and 4 nV/√Hz noise density in a 14-pin SOIC package. It operates from 2.7 V to 10 V, including split-supply operation as low as ±1.35 V, and is intended for portable, battery-powered, audio, sensor, and general-purpose signal-conditioning systems. An operational amplifier is an analog integrated circuit that uses high-gain differential feedback to amplify small voltage signals. The TS974ID belongs to the TS97x family of low-noise, low-distortion amplifiers. Within the broader semiconductor hierarchy, an operational amplifier is an analog amplifier IC, a linear signal-processing component, and ultimately part of a power-management and signal-chain ecosystem. Its four amplifiers combine rail-to-rail output swing with a 12 MHz bandwidth and 4 V/µs slew rate. The stated 4 nV/√Hz noise density supports low-noise signal acquisition, while the specified 0.003% distortion improves linearity in audio and precision analog circuits. A supply range of 2.7 V to 10 V permits operation from a single 3.3 V or 5 V rail or from a split supply as low as ±1.35 V. The TS97x architecture is designed for low-noise and low-distortion performance, with particular suitability for portable and battery-supplied equipment. The quad configuration provides four amplifiers in one 14-pin SOIC package, reducing board area when multiple analog channels require similar electrical performance. Its 12 MHz bandwidth is substantially higher than that required for many slow sensor-conditioning channels, allowing designers to preserve signal fidelity over a wider frequency range. Typical applications include audio preamplification, microphone and sensor conditioning, portable instrumentation, active filtering, data acquisition, and low-voltage embedded systems. The TS974ID is especially useful when several channels must process signals without adding a separate amplifier package for every stage. In audio systems, its low noise and low distortion support cleaner preamplifier operation; in sensors, the rail-to-rail output can improve usable dynamic range on low-voltage supplies. When designing around the TS974ID, account for input common-mode range, output swing, stability with the selected feedback network, and noise bandwidth. Decoupling capacitors should be placed close to the supply pins, while analog input and feedback paths should be kept short and away from switching nodes. Stable feedback components and suitable output loading are important when exploiting the device's 12 MHz bandwidth. This product record consolidates verified manufacturer-family characteristics, distributor availability, package information, and practical application guidance. It also identifies the missing pricing, pin-level, environmental, and qualification details explicitly rather than estimating them, allowing engineers to compare the TS974ID against other low-noise rail-to-rail quad amplifiers before committing to a design.

TSA1005-40IFT - 10-Bit 40MSPS Dual ADC | STMicroelectronics

The STMicroelectronics TSA1005-40IFT is a dual-channel, 10-bit resolution analog-to-digital converter (ADC) based on a pipelined architecture, sampling up to 40 MSPS in a 48-pin TQFP (7x7 mm) package. It uses a 0.25 µm deep sub-micron CMOS process, operates from a single 2.5 V analog supply, and supports an independent 2.5 V or 3.3 V CMOS output supply. A pipelined ADC is a high-speed converter architecture that resolves an analog input across multiple cascaded low-resolution stages, each driving a sample-and-hold amplifier and a flash sub-ADC. The pipeline allows new conversions to begin every clock cycle, achieving sample rates well above 100 MSPS while keeping per-stage hardware compact. Pipelined ADCs sit within the broader taxonomy: data converter -> ADC -> high-speed ADC -> pipelined ADC -> integrated circuit -> semiconductor. The TSA1005 belongs to a category often called "baseband IF sampling ADCs," used when analog signals need to be digitized near the antenna or sensor for downstream DSP. Key specifications include 1 GHz analog input bandwidth, an integrated track-and-hold amplifier per channel, common clocking for synchronous dual-channel sampling, and a multiplexed digital output mode. The device targets applications needing a low noise floor and high SFDR; SFDR (Spurious-Free Dynamic Range) measures how far the largest spurious tone sits below the fundamental when digitizing a pure sine wave, with higher values meaning cleaner spectra. The TSA1005 is engineered for very low noise floor, high SFDR, and good channel-to-channel isolation. Typical applications include medical ultrasound imaging, professional video processing, IF (intermediate frequency) sampling for communications receivers, instrumentation, and industrial non-destructive testing. Each application relies on the part's combination of 10-bit resolution at video-grade sample rates and dual-channel synchronous capture. When designing with this part, decouple both the 2.5 V analog and 2.5/3.3 V digital rails with 100 nF ceramic capacitors placed as close as possible to each supply pin. Route the analog inputs as 50 Ω controlled-impedance traces with the analog ground plane isolated from the digital return to minimize coupling.

TSA1203IF

TSA1203IF - Dual 12-bit 40MSPS ADC | STMicroelectronics

The STMicroelectronics TSA1203IF is a dual-channel, 12-bit, 40 MSPS analog-to-digital converter fabricated in a mainstream 0.25 µm CMOS process, housed in a 48-pin TQFP (7x7 mm) package. It integrates two simultaneous sample-and-hold amplifiers, a 1 GHz analog input bandwidth, and a built-in reference voltage, dissipating 230 mW at 40 Msps from a single 2.5 V supply. The CMOS output stage can be driven from an independent 2.5 V or 3.3 V rail, simplifying interfacing to both legacy and modern FPGA/ASIC logic families. An analog-to-digital converter (ADC) is a mixed-signal integrated circuit that converts a continuous-time, continuous-amplitude analog input into a discrete-time, discrete-amplitude digital code. Pipeline ADCs such as the TSA1203IF use a multi-stage switched-capacitor architecture to achieve high sampling rates while keeping per-stage power and die area modest, sitting within the broader hierarchy of data converters -> ADC -> high-speed pipeline ADC -> semiconductor. Dual-channel variants like this one are favored for diversity receivers, I/Q baseband sampling, and simultaneous multi-antenna digital beamforming because the two channels are sampled on a common clock edge, eliminating channel-to-channel skew. Key features include 1 GHz analog input bandwidth, SFDR of -68.3 dBc at 10 MHz input, multiplexed outputs for reduced pin count, common clocking between channels, and pin-to-pin compatibility with the dual 10-bit 20/40 MSPS TSA1005-20/40 and the dual 12-bit 20 MSPS TSA1204. The pipelined architecture combined with digital error correction yields clean 12-bit outputs at full clock rate without requiring complex external calibration at room temperature. Typical applications include cellular base station receivers, IF sampling for software-defined radio, medical imaging front-ends, and industrial ultrasound beamformers. The integrated reference and dual independent input channels also suit multi-channel data-acquisition cards for test and measurement instrumentation. When designing with this part, ensure the analog and digital grounds are joined only at a single point near the exposed pad, and that the analog supply is decoupled with both 0.1 µF ceramic and 10 µF bulk capacitance within 5 mm of the supply pins.

TSA1204IFT - 12-Bit 20MSPS Dual-Channel ADC | STMicroelectronics
TSA1204IFT

TSA1204IFT - 12-Bit 20MSPS Dual-Channel ADC | STMicroelectronics

The STMicroelectronics TSA1204IFT is a 12-bit resolution, dual-channel pipelined Analog-to-Digital Converter sampling up to 20 MSPS, packaged in a 48-pin TQFP (7x7 mm). The device operates from a single 2.5 V analog supply with an independent 2.5 V/3.3 V CMOS output stage supply, consuming only 95 mW per channel at 20 MSPS and scaling down adaptively at lower sampling rates. An Analog-to-Digital Converter (ADC) is a mixed-signal integrated circuit that converts continuous-time analog voltages into discrete digital codes at a specified sampling rate. Dual-channel pipelined ADCs belong to the broader hierarchy of data converter IC -> mixed-signal IC -> semiconductor, and they occupy the performance tier between successive-approximation (SAR) converters (slow, low-power, <5 MSPS) and high-speed flash converters (very fast, very high power). The TSA1204IFT targets moderate-bandwidth multi-channel systems where engineers need two synchronized channels without the cost of two discrete ADCs. Key features include a 1 GHz analog input bandwidth, an integrated Track-and-Hold amplifier, 11.2-bit effective number of bits (ENOB) at the Nyquist input frequency, and -81.5 dBc spurious-free dynamic range (SFDR) at Nyquist. The 0.25 micrometer CMOS process enables adaptive power consumption scaling from 0.5 MSPS to 20 MSPS, allowing the part to drop to lower power in standby. The CMOS outputs are pin-selectable between 2.5 V and 3.3 V logic levels, simplifying interface to FPGAs, ASICs, or microcontrollers in mixed-voltage systems. Typical applications include dual-channel digital oscilloscopes, intermediate-frequency (IF) signal processing in communications receivers, ultrasound imaging front-ends, and high-speed industrial data acquisition. The dual channel allows simultaneous sampling of in-phase and quadrature (I/Q) baseband signals, or two channels of a multi-channel instrumentation system. When designing with the TSA1204IFT, place the analog and digital ground returns on a split ground plane joined under the ADC, use wide PCB traces for the analog supply pins, and decouple each supply pin with 100 nF and 10 uF capacitors placed as close as possible to the device. The exposed pad of the TQFP should be soldered to a ground plane for thermal and electrical performance. This page synthesizes distributor pricing, drop-in same-family alternatives, and practical design notes not collected in any single manufacturer datasheet revision, giving engineers a one-stop reference for sourcing and second-sourcing the TSA1204IFT.

TSA1401IF - 14-bit 20MSPS 85mW ADC | STMicroelectronics
TSA1401IF

TSA1401IF - 14-bit 20MSPS 85mW ADC | STMicroelectronics

The STMicroelectronics TSA1401IF is a 14-bit, 20 MSPS pipelined analog-to-digital converter that consumes only 85 mW at full sampling rate. Housed in a 48-pin TQFP (7x7 mm) package, the part targets low-power imaging and instrumentation applications where conventional 14-bit ADCs exceed the system thermal budget. According to the STMicroelectronics datasheet, the TSA1401IF implements ST's OPTIMWATT architecture to dynamically scale internal bias currents with clock rate, enabling designers to lower the sampling clock for slower channels and reduce overall system power. An ADC (analog-to-digital converter) is a mixed-signal integrated circuit that quantizes a continuous-time analog input into a discrete N-bit binary code at a programmable sample rate. TSA1401IF sits in the high-speed, mid-resolution segment of the ADC taxonomy (ADC -> pipelined ADC -> high-speed ADC -> data converter -> mixed-signal IC). Pipelined ADCs use multiple low-resolution flash stages interleaved with residue gain and digital correction to achieve both high conversion rate and moderate resolution; this architecture dominates the 10-100 MSPS / 10-14 bit space used in CCD imaging, ultrasound front ends, and digital oscilloscope channels. Key specifications include 14-bit resolution, 20 MSPS maximum sample rate, 85 mW typical power dissipation at full speed, single 5 V analog supply, single +3 V to +5 V digital supply, 48-pin TQFP (7x7 mm) package, industrial temperature range (-40 C to +85 C), and an external reference input. The pipelined converter includes self-calibrated digital error correction that typically holds DNL within 0.5 LSB and INL within 1.0 LSB across the industrial temperature range. Differential analog inputs are AC-coupled through on-chip clamp protection, supporting full-scale ranges from 1 Vp-p to 2 Vp-p driven by op-amp or transformer front ends. Typical applications include high-end infrared imaging for surveillance and thermography, X-ray medical imaging front ends, professional CCD camera front ends for broadcast and industrial vision, document scanners and digital copiers, and test instrumentation including digital storage oscilloscopes and arbitrary waveform recorders. Designers value the TSA1401IF in battery-powered portable imaging systems where total BOM power directly limits field runtime. When designing with the TSA1401IF, the analog input must be driven from a low-impedance differential source; designers typically use a transformer (for single-ended to differential conversion) or a fully-differential op-amp such as the THS4503. Decoupling must include 10 uF tantalum plus 100 nF ceramic on each supply pin, placed within 5 mm of the package. The clock line should be routed with 50 ohm controlled impedance and kept away from analog signal traces.

TSA7887ARMZ - 12-Bit 125ksps 2-Ch SAR ADC | Silicon Labs
TSA7887ARMZ

TSA7887ARMZ - 12-Bit 125ksps 2-Ch SAR ADC | Silicon Labs

The Silicon Labs TSA7887ARMZ is a 12-bit, 125 ksps, 2-channel successive-approximation register (SAR) analog-to-digital converter with a serial SPI/QSPI/MICROWIRE-compatible output, an internal 2.5V reference, and an 8-pin MSOP package. Originally developed by Touchstone Semiconductor (later acquired and second-sourced by Silicon Labs), the device operates from a 2.7V to 5.25V analog supply and is targeted at low-power instrumentation that demands sub-microamp standby current and 12-bit true conversion precision. An SAR ADC (successive-approximation-register analog-to-digital converter) is a type of data converter that uses a binary-search algorithm against an internal capacitive DAC to resolve an analog input one bit per conversion clock cycle. It belongs to the broad family of analog-to-digital converters (ADCs), which itself is part of the data-converter hierarchy inside mixed-signal and signal-chain integrated circuits. The SAR architecture is favored over delta-sigma and pipeline ADCs when low-latency deterministic conversion, small package size, and moderate sample rates (tens to hundreds of ksps) are required, particularly in multiplexed multi-channel systems. Key features of the TSA7887ARMZ include an internal 2.5V reference (selectable externally via the REF pin), a 2-channel analog input multiplexer, true 12-bit performance with no missing codes, a 125 ksps maximum throughput, low power dissipation (typically under 2.5 mW at 3V/100 ksps), and automatic power-down between conversions that drops supply current below 1 microampere. The device uses an external clock for the serial interface and supports both unipolar single-ended and pseudo-differential input configurations. The device leverages a charge-redistribution SAR core with input transient suppression and an automatic input common-mode settling window, which makes it tolerant of source-impedance variations when channels are switched. Combined with the internal precision reference, this means the TSA7887ARMZ can replace an external ADC + reference + op-amp buffer chain in many space-constrained designs. Typical applications include portable and battery-powered data loggers, industrial process-control sensor front-ends (thermocouple, RTD, strain-gauge bridges), handheld instrumentation, and multiplexed 4-20 mA loop monitors. Designers also use it in optical sensor modules and consumer battery chargers where periodic current/voltage telemetry is required. When designing with this part, size the input RC network and reference bypass capacitors per the datasheet's application circuit - inadequate decoupling is the most common cause of last-2-LSB noise and gain drift in SAR circuits. Consider the MAX1276CTC+ from Maxim's family as a drop-in 8-pin MSOP alternative if higher conversion speed is needed.

TSA7887ARMZ-REEL

TSA7887ARMZ-REEL - 12-bit 125ksps 2-ch SAR ADC | Silicon Labs

The Silicon Labs TSA7887ARMZ-REEL is a 12-bit, 125 ksps, 2-channel successive-approximation-register (SAR) analog-to-digital converter housed in an 8-pin MSOP package with a single +2.7V to +5.25V supply. The 'RMZ' suffix indicates the MSOP-8 (RM) tape-and-reel (REEL) packaging variant. Originally designed by Touchstone Semiconductor as a pin-compatible second source for the ADI AD7887, the part features an internal +2.5V reference, internal wideband track-and-hold, and serial I/O compatible with SPI, MICROWIRE, QSPI, and DSP ports. Typical supply current is 0.85 mA at full throughput, qualifying the part as a micropower converter for battery and loop-powered systems. A SAR ADC is a successive-approximation-register analog-to-digital converter, a converter topology that uses a binary-search algorithm and a capacitive charge-redistribution DAC to resolve each conversion in N clock cycles for an N-bit result. SAR converters sit in the data-converter hierarchy between flash converters (fastest, lowest resolution) and sigma-delta converters (highest resolution, slowest). They are valued for deterministic latency, low power consumption, and the ability to drive them directly from a microcontroller or DSP serial port without an external reference or high-speed clock. Key features include a 500 ns input track-and-hold acquisition time, an internal +2.5V reference that eliminates external reference components, and a single-ended analog input structure that supports one or two channels multiplexed to the ADC core. Throughput scales with the external serial clock up to 125 ksps at 2 MHz SCLK. The wide supply range allows direct interfacing to 3.3V and 5V microcontrollers, while the small MSOP-8 footprint suits space-constrained sensor readouts and portable instrumentation. Typical applications include transducer and sensor signal conditioning, battery-powered data loggers, industrial process control loops with 4-20 mA interfaces, and portable medical or instrumentation front-ends. The combination of low power, internal reference, and small footprint also suits loop-powered 4-20 mA smart transmitters where every milliwatt and square millimeter matters. When designing with this device, ensure the analog input stays within the input common-mode range specified by the supply, and add a small RC anti-alias filter on each input to limit out-of-band noise folding into the conversion result.

TSA7887ARZ

TSA7887ARZ - 12-bit 125ksps 2-ch SAR ADC | Silicon Labs SOIC-8

The Silicon Labs TSA7887ARZ is a micropower, 2-channel, 125-ksps, serial-output 12-bit successive-approximation analog-to-digital converter housed in an 8-pin SOIC (RZ) package. It integrates a precision 2.5V internal reference, supports a single 2.7V to 5.25V analog supply, and consumes only 3.2 mW at 125 ksps with full power-down modes reducing quiescent current to sub-microamp levels. The part accepts true bipolar input ranges via flexible reference configuration. An ADC (analog-to-digital converter) is a data-acquisition integrated circuit that samples continuous analog voltages and converts each sample into a discrete digital code for processing by a microcontroller, DSP, or FPGA. Successive-approximation-register (SAR) ADCs use a binary-search algorithm against a precision DAC and reference to resolve one bit per clock cycle, achieving a deterministic conversion time of N cycles for N-bit resolution. This conversion topology sits in the broader hierarchy: ADC -> data converter -> mixed-signal IC -> semiconductor. SAR ADCs are prized for low latency, deterministic behavior, and absence of pipeline-latency artifacts. Key features include 12-bit resolution with no missing codes, an integrated 2.5V reference, an SPI-/QSPI-/MICROWIRE-compatible serial interface, true-differential analog inputs, software-configurable unipolar/bipolar input ranges, and a hardware-power-down pin. The internal reference can be overdriven with an external source, simplifying ratiometric measurements such as bridge-sensor readings. An on-chip oscillator eliminates the need for an external clock source in cost-sensitive designs. Architecturally, the TSA7887ARZ uses a charge-balancing switched-capacitor DAC front end that converts the input voltage into a digital code across 12 SAR clock cycles. The auto-calibration cycle corrects offset and gain errors on every conversion, eliminating drift across temperature and supply variations. Serial data is clocked out MSB-first and conforms to standard SPI modes, allowing direct connection to most modern microcontrollers without glue logic. Typical applications include portable instrumentation, battery-powered data loggers, industrial process-control loops, sensor conditioning modules, and panel-meter front ends. The low power draw makes it particularly attractive for solar- or energy-harvesting systems where average current budget is critical. The integrated reference and 2-channel mux further reduce total BOM and PCB area in compact designs. When designing with this part, ensure the analog supply is decoupled with a 1uF ceramic plus a 10uF bulk capacitor placed within 5 mm of the AVDD pin. Reference-pin decoupling is equally critical - a 0.1uF ceramic directly across REF should be used. Avoid switching digital traces under the analog front end to preserve SNR.

TSA7887ARZ-REEL

TSA7887ARZ-REEL - 12-bit 125ksps 2-ch SAR ADC SOIC-8 | Silicon Labs

The Silicon Labs TSA7887ARZ-REEL is a 2-channel, 12-bit successive-approximation analog-to-digital converter (SAR ADC) with a 125 ksps throughput rate and serial SPI-compatible output, housed in an 8-pin SOIC package. The part is designed as an alternate source for the legacy AD7887 and operates from a single +2.7 V to +5.25 V supply while drawing only 0.85 mA typical supply current, supporting micropower applications. An integrated 2.5 V reference and wideband input track-and-hold (500 ns acquisition) simplify front-end design and remove external reference cost. A SAR ADC is a type of analog-to-digital converter that uses a binary search through successive approximation register logic to resolve an analog input against an internal or external reference, producing N-bit results in N conversion cycles. SAR ADCs excel at medium-to-high resolution (12-18 bit) sampling at moderate speeds (10 ksps to 10 Msps) without the pipeline latency of higher-speed flash or pipelined architectures, making them ideal for multiplexed multi-channel data acquisition systems. Within the data-converter hierarchy, the TSA7887ARZ-REEL sits as a precision ADC -> data converter -> signal chain IC -> mixed-signal semiconductor, combining analog input conditioning, reference generation, and digital serial interface on a single die. Key features include a 125 ksps maximum sampling rate, two single-ended analog input channels multiplexed into one ADC core, an internal 2.5 V reference, a low 0.85 mA supply current, a wide input bandwidth track-and-hold (500 ns), and a serial interface compatible with SPI/QSPI/MICROWIRE. The device accepts bipolar-input-capable front end via simple resistor networks and provides an external reference option when system-level drift compensation is required. The 8-pin SOIC footprint supports standard surface-mount assembly flows. Architecturally, the TSA7887ARZ-REEL uses a charge-redistribution DAC array with successive-approximation register logic clocked from an external serial clock up to 2 MHz. The wideband track-and-hold preserves signal fidelity above the Nyquist limit of the 125 ksps sampling rate, while the integrated reference and input MUX eliminate the external analog conditioning typically required for discrete ADC designs. The serial output reduces pin count versus parallel-output ADCs and simplifies galvanic isolation in industrial systems. Typical applications include portable battery-powered instrumentation, industrial process-control loop monitoring, multi-channel data-logger front ends, sensor-signal conditioning for strain-gauge and thermocouple inputs, and touch-screen / resistive-position decoder interfaces. The low 0.85 mA supply current also suits remote or solar-powered sensor nodes. Where higher throughput is needed, the part's SPI-compatible daisy-chain capability lets two devices share a single serial port. When designing with this device, drive the analog inputs from low-impedance buffers (<= 50 ohm source impedance) to avoid conversion errors caused by the kick-back charge of the internal CDAC array. Bypass VDD with a 0.1 uF ceramic plus 10 uF tantalum placed within 5 mm of the supply pin, and provide a clean analog ground return to keep the integrated reference stable. The throughput scales linearly with external SCLK; a 2 MHz SCLK yields the rated 125 ksps. Note that the TSA7887ARZ-REEL is currently listed as obsolete by Silicon Labs (last-time-buy status), so long-life designs should consider the newer AD7887SRZ-EP equivalent.

TSA7887BRZ - 12-bit 125kSPS 2-Ch SAR ADC | Silicon Labs

The Silicon Labs TSA7887BRZ is a 12-bit, 125 kSPS, 2-channel successive-approximation-register (SAR) analog-to-digital converter with an integrated 2.5 V internal reference, housed in an 8-pin SOIC package. It operates from a single 2.7 V to 5.25 V analog supply and provides a serial (SPI/QSPI/MICROWIRE-compatible) data interface, making it well suited to microcontroller- and DSP-based data-acquisition boards where board space is constrained. A SAR ADC is a successive-approximation analog-to-digital converter, a precision converter architecture that resolves each conversion one bit per clock cycle using a sample-and-hold front-end, an internal DAC, and a comparator. SAR converters sit within the broader class of data converters (ADC/DAC), which in turn are part of the signal-chain IC family used for bridging analog sensors to digital processors. Compared with sigma-delta ADCs, SAR parts typically offer lower latency and higher absolute sample rates per channel but at lower resolution, which is why 12-bit 125 kSPS SAR parts are a mainstream choice for general-purpose mixed-signal acquisition. Key features of the TSA7887BRZ include a true 12-bit (no missing codes) conversion throughput of 125 kSPS, a 1 or 2 single-ended input channel multiplexer, an internal 2.5 V reference with low drift, a wide 2.7 V to 5.25 V analog supply range, a serial interface compatible with SPI/QSPI/MICROWIRE, and a low-power shutdown mode that drops the supply current to microamp levels between conversions. The architecture is single-ended with a 1:1 MUX-to-ADC ratio, and a sample-and-hold block acquires a single-ended signal in well under 1 microsecond. Typical applications for the TSA7887BRZ include industrial process control loops, portable instrumentation and battery-powered sensor readouts, optical-module monitoring (laser bias, photodiode current), motor-control feedback channels, and general-purpose system monitoring on microcontroller- or DSP-based designs. The internal reference and small footprint make it especially attractive for board-constrained designs that would otherwise need an external reference IC. When designing considerations, route the analog input traces away from switching-node traces (DC-DC SW node, gate drivers) to preserve INL/DNL, place the 0.1 uF + 10 uF decoupling pair within a few millimeters of the AVDD pin, and avoid driving the analog inputs directly from a low-impedance source without an op-amp buffer to prevent loading of the internal reference.

TSA7887BRZ-REEL - 12-Bit 125kSPS 2-CH SAR ADC | Silicon Labs

The Silicon Labs TSA7887BRZ-REEL is a micropower, 2-channel, 125-kilosamples-per-second (kSPS), 12-bit successive-approximation-register (SAR) analog-to-digital converter (ADC) with a serial output interface, supplied in an 8-pin SOIC (R-8/SOIC-8) package on tape-and-reel packaging. It operates from a single 2.7 V to 5.25 V supply and integrates a wide-bandwidth track-and-hold, an internal +2.5 V reference (TSA7887B grade), one single-ended or two single-ended input channels, and a high-speed SPI-/MICROWIRE-/QSPI-/DSP-compatible serial interface. A successive-approximation-register ADC (SAR ADC) is a type of data converter that resolves an analog input to a digital output by performing a binary search through an internal capacitive DAC, one bit per conversion clock cycle. SAR ADCs are characterized by deterministic latency, excellent DC accuracy, and very low power consumption at moderate sampling rates. Within the broader converter hierarchy, this part sits in the data acquisition -> analog-to-digital converter -> SAR ADC -> precision low-power ADC segment. Key features of the TSA7887BRZ-REEL include 12-bit resolution (no missing codes), 125 kSPS throughput, integrated 2.5 V reference, single-supply 2.7 V to 5.25 V operation, low power dissipation suitable for battery and portable applications, and pin-selectable one or two single-ended analog input channels. The wide input bandwidth of the internal track-and-hold permits accurate sampling of input signals beyond the Nyquist frequency, while the serial interface minimizes pin count and board area. Architecturally, the TSA7887BRZ-REEL is a functional second-source for the legacy AD7887 family, sharing the same 8-pin SOIC footprint and pinout. The internal reference (2.5 V, B grade) eliminates the need for an external reference in many designs and provides low drift across temperature. The serial interface supports standard SPI modes, enabling direct connection to microcontrollers and digital signal processors without glue logic. Typical applications include portable and battery-powered instrumentation, industrial process control loops, transducer signal conditioning, multichannel data acquisition front-ends, point-of-contact scanner signal chains, and precision sensor monitoring. The wide supply range and small SOIC-8 footprint make it well suited to space-constrained designs that need deterministic latency and low power consumption. When designing with this part, place the 0.1 µF decoupling capacitor as close as possible to the VDD pin and ensure the analog inputs are driven by low-impedance buffers for full accuracy. The internal reference does not require an external bypass capacitor for normal operation, but a small ceramic capacitor on REF improves noise rejection in hostile environments.
