TS912IN

TS912IN - Dual Rail-to-Rail CMOS Op Amp | STMicroelectronics

The STMicroelectronics TS912IN is a dual rail-to-rail CMOS operational amplifier with two amplifier channels, a 2.7 V to 16 V supply range, and an 8-pin Mini DIP package. The device supports single-supply or dual-supply operation, with rail-to-rail input and output voltage ranges. According to the manufacturer datasheet, its typical input bias current is only 1 pA, maximum input offset voltage is 2 mV, and supply current is approximately 200 µA per amplifier at a 3 V supply. These characteristics make the TS912IN suitable for low-power instrumentation, sensor interfaces, and signal-conditioning circuits that require low input bias and flexible supply operation. A CMOS operational amplifier is a voltage amplifier whose differential input controls the voltage applied to its output. Rail-to-rail input and output ratings allow the amplifier to operate close to the positive and negative supply rails, increasing the usable output range in single-supply systems. In the electronics hierarchy, the TS912IN is a dual operational amplifier, which belongs to the broader class of analog amplifier ICs and ultimately to integrated circuits used for analog signal processing. Key features include two independent amplifier channels, rail-to-rail input and output operation, and a 2.7 V to 16 V total supply range. The 1 pA typical input bias current is particularly useful for high-impedance sources because it minimizes source-loading error. Maximum input offset voltage of 2 mV supports accurate amplification of signals near the lower end of the input range. Operation from a 3 V supply at approximately 200 µA per amplifier also helps limit power consumption in battery-operated equipment. The TS912IN uses CMOS input circuitry to provide low bias current and low supply consumption. Rail-to-rail input behavior is important when the signal can approach either supply rail, while rail-to-rail output capability allows the output to use much of the available supply voltage. Designers should still account for output-current limits, load impedance, input common-mode behavior, and output-voltage headroom under the selected supply voltage and load conditions. Typical uses include low-power sensor signal conditioning, portable measurement instruments, battery-powered monitoring, and general-purpose analog filtering. The dual configuration allows one package to provide two amplifier channels for gain stages, buffers, comparators, or active filters. When the source impedance is high, the 1 pA typical bias current reduces loading, although PCB leakage and guard-ring techniques may still be necessary in demanding measurements. When designing around the TS912IN, use stable bypass capacitance at the supply pins and keep feedback components close to the amplifier pins to minimize parasitic effects. Confirm the required output swing, load, input range, and noise performance against the manufacturer datasheet before finalizing a high-gain or precision application. This page consolidates the verified manufacturer descriptions, distributor references, package information, technical characteristics, and substitution constraints for the TS912IN. It also distinguishes verified data from unavailable pricing, compliance, and pin-mapping details, helping engineers evaluate the amplifier without treating unverified substitute parts as drop-in equivalents.

TS914ID - Quad Rail-to-Rail CMOS Op Amp | STMicroelectronics
TS914ID

TS914ID - Quad Rail-to-Rail CMOS Op Amp | STMicroelectronics

STMicroelectronics TS914ID is a quad rail-to-rail CMOS operational amplifier with a 1.4 MHz gain-bandwidth product, operating from 2.7 V to 16 V and supplied in a 14-pin SOIC package. The device accepts single or dual supply voltages and supports rail-to-rail input and output operation, allowing signals to approach either supply rail. Its extremely low 1 pA typical input bias current suits high-impedance sensing circuits, while the 2 mV maximum input offset voltage provides adequate precision for general-purpose analog signal conditioning. A CMOS operational amplifier is a voltage-controlled, high-gain analog building block whose differential input is amplified relative to ground or another reference voltage. The TS914 belongs to the operational-amplifier hierarchy, combining four amplifiers in one integrated circuit. It is designed for low-power, single-supply and dual-supply systems where four independent analog channels can be implemented in one compact 14-pin SOIC package. Key features include four amplifier channels, rail-to-rail input and output ranges, a 2.7 V to 16 V supply-voltage range, and a 1.4 MHz gain-bandwidth product. The typical input bias current of 1 pA is particularly valuable when source impedances are high, because it minimizes the voltage error caused by bias current. The reported 200 µA supply current per amplifier at 3 V also supports battery-powered and portable equipment when the required bandwidth is moderate. The TS914's CMOS input stage enables operation close to the supply rails and supports low input bias current. Its 1.4 MHz bandwidth is appropriate for general-purpose amplification, filtering, buffering, and signal conditioning rather than high-speed precision instrumentation. Because the maximum offset voltage is specified as 2 mV, applications demanding sub-millivolt accuracy require additional calibration or a more precise amplifier. Typical uses include four-channel sensor interfaces, low-frequency active filters, audio and communication signal conditioning, portable instrumentation, and industrial control modules. Placing all four channels in one SOIC package reduces board area and external component count. Input common-mode and output swing limits, output-current capability, noise, and stability should still be checked against the manufacturer datasheet before fixing the supply voltage and external network. For reliable single-supply operation, keep the input common-mode voltage within the supported range, place input and feedback components close to the device, and provide suitable bypassing at each supply pin. Decoupling requirements and compensation values must follow the manufacturer datasheet rather than generic assumptions. If the source resistance is high, account for input bias-current and capacitance errors, and confirm that the selected feedback topology remains stable at the intended gain. This product page consolidates verified manufacturer and distributor information with package, application, replacement, and design guidance. It distinguishes verified parameters from information that still requires datasheet review, helping engineers evaluate TS914ID without mistaking generic amplifier assumptions for guaranteed TS914ID characteristics.

TS914IN - 4-Channel Rail-to-Rail Op Amp | STMicroelectronics

STMicroelectronics TS914IN is a four-circuit, rail-to-rail CMOS operational amplifier designed for single or dual supply operation, with a 16 V maximum supply voltage, 1 pA typical input bias current, and a 2 mV maximum input offset voltage. The device is supplied in a 14-pin through-hole DIP package, allowing one package to implement four amplifier channels. A CMOS operational amplifier is a voltage-controlled, high-gain analog signal-processing component used for buffering, amplification, sensing, filtering, and feedback control. The TS914IN belongs to the operational amplifier hierarchy within analog integrated circuits, where its rail-to-rail input and output capability makes it suitable for systems whose signal levels approach the available supply rails. Key features include four amplifier circuits, rail-to-rail input and output operation, support for single or dual power supplies, very low 1 pA typical input bias current, and low input offset voltage no greater than 2 mV. According to the STMicroelectronics manufacturer datasheet, the device is intended for applications operating from a single supply or from dual supplies up to 16 V. The low input bias current is especially useful when the amplifier is connected to high-impedance sensors, because the amplifier contributes minimal loading to the source. Rail-to-rail behavior also broadens the usable input and output range in low-voltage systems. The trade-off is that the 14-pin DIP package is larger than modern surface-mount packages, making TS914IN more appropriate for through-hole, legacy, industrial, and prototyping assemblies. Typical uses include battery-powered instrumentation, sensor interfaces, low-voltage signal conditioning, sample-and-hold circuits, active filters, and general-purpose analog control systems. Its four independent channels can reduce the number of packages required when a board needs several similar low-power amplifier functions. When designing around TS914IN, verify input and output common-mode limits, output-current capability, operating-temperature limits, and stability requirements against the manufacturer datasheet for the exact operating conditions. Input bias, offset, and supply currents should be checked with the source impedance and signal bandwidth, particularly in high-impedance precision measurements. This page consolidates verified manufacturer and distributor information, package and pin details, replacement constraints, comparison data, and application-specific engineering guidance. It distinguishes confirmed specifications from unavailable values so engineers can make sourcing and PCB-retention decisions without relying on unsupported assumptions.

TS921ID - 4MHz High-Output RRIO Op Amp | STMicroelectronics

The STMicroelectronics TS921ID is a single rail-to-rail input and output BiCMOS operational amplifier optimized for 3 V and 5 V operation, with a 4 MHz gain-bandwidth product, 1.3 V/us slew rate, and 80 mA output-current capability in an 8-pin SOIC package. An operational amplifier is a voltage-controlled differential amplifier that uses high open-loop gain to amplify small input signals. The TS921 belongs to the rail-to-rail input/output, or RRIO, family, allowing its input common-mode range and output swing to approach the supply rails. This makes it useful for low-voltage battery-powered equipment, sensor interfaces, audio stages, industrial controls, and portable instruments where the signal can occupy much of the available supply range. The TS921's principal features include low input noise of 9 nV/sqrt(Hz), a 4 MHz gain-bandwidth product, 1.3 V/us slew rate, and an output stage capable of delivering 80 mA. The manufacturer identifies the device as optimized and fully specified for 3 V and 5 V supplies, while verified distributor data also gives a 2.7 V to 12 V operating-voltage range. Rail-to-rail operation reduces the need for separate positive and negative supply rails in single-supply designs. The BiCMOS process combines bipolar input characteristics with CMOS output circuitry. In practical signal chains, the TS921 can condition low-level sensor outputs, buffer precision ADC inputs, or provide general-purpose gain. Its 80 mA output capability is useful for driving moderate loads, although sustained heavy loading can reduce output swing and increase power dissipation. The 4 MHz bandwidth supports applications requiring moderate rather than high-frequency closed-loop performance. Typical uses include battery-operated instrumentation, low-voltage audio, industrial sensor conditioning, active filters, and portable measurement equipment. The SOIC-8 format supports conventional surface-mount assembly, while the manufacturer datasheet provides the authoritative pin connection and recommended application information for layout and decoupling decisions. For single-supply operation, reserve output headroom for the load and check the input common-mode range across the complete signal excursion. Place the supply bypass capacitor close to the positive and ground pins, and use short, low-impedance feedback routes to limit parasitic feedback and preserve stability. This product page combines the verified manufacturer and distributor information with package, application, comparison, and design guidance. It identifies where TS921ID fits, highlights the 4 MHz bandwidth and 80 mA output-current capabilities, and clearly separates confirmed data from engineering details that require additional verification.

An operational amplifier, or op amp, is a high-gain analog building block used to amplify, buffer, compare, filter, and control signals. The TS921IN belongs to the operational-amplifier hierarchy, which falls under analog amplifier ICs and broader semiconductor signal-conditioning devices. Its rail-to-rail input and output architecture is useful when the usable input or output range must extend close to the supply rails. Key characteristics include a 4 MHz gain-bandwidth product, 1 V/µs slew rate, low input-referred noise density of 9 nV/√Hz, and typical output current of 80 mA. The single-amplifier configuration allows a PCB footprint to remain compact, while the 8-DIP package provides straightforward through-hole assembly. The listed operating temperature range is -40°C to +125°C, supporting industrial-temperature applications. The TS921IN combines rail-to-rail signal handling with relatively high bandwidth and output-drive capability. Its low-noise specification is particularly useful for low-level audio, instrumentation, sensor-interface, and general analog signal-conditioning circuits. The 80 mA output current also allows the amplifier to drive more demanding loads than a typical comparator-oriented or ultra-low-power op amp, provided the supply voltage and thermal limits remain satisfied. Typical uses include low-level sensor amplification, active filtering, audio preamplification, buffer stages, threshold and comparator-style interfaces, and general industrial control circuitry. It can also serve as a rail-to-rail input/output buffer in systems where the input signal approaches either supply rail. Designers should still verify stability, output swing, load capability, and noise performance against the complete circuit requirements. A key design consideration is the trade-off between bandwidth, noise, and output drive. The TS921IN is more capable than a low-power, low-bandwidth amplifier, but it is not necessarily the optimal choice for every precision or micropower design.

STMicroelectronics TS924ID is a four-circuit, rail-to-rail BiCMOS operational amplifier with an 80 mA output-current rating, 80 dB CMRR, and a maximum bias current of 0.1 µA, supplied in a 14-pin small-outline package. The device is optimized for 3 V and 5 V operation and is intended for low-voltage signal conditioning, audio, portable equipment, and general-purpose analog systems. An operational amplifier is an analog integrated circuit that amplifies the voltage difference between its non-inverting and inverting inputs. A quad package contains four independent amplifier sections, allowing one TS924ID to implement four amplifier channels in a single 14-pin package. Rail-to-rail input and output operation helps preserve signal range in low-voltage systems where conventional amplifier stages may approach their supply limits. Key features include four amplifier circuits, rail-to-rail operation, an 80 mA cited output-current capability, 80 dB common-mode rejection ratio, and a maximum input bias current of 0.1 µA. The TS924 family is described as a low-noise, low-distortion BiCMOS design. Its low bias current is particularly useful in high-impedance sensing paths, while the rail-to-rail characteristics support compact, low-voltage equipment. The bipolar input stage and CMOS output stage form the BiCMOS architecture used in the TS924 family. Input bias current, common-mode rejection ratio, offset voltage, output-current capability, noise, and distortion are the principal parameters to check when comparing it with other quad low-voltage operational amplifiers. The verified TS924ID information cites a maximum offset of 5000 µV, a maximum bias current of 0.1 µA, and an 80 mA output-current feature. Typical uses include low-voltage audio signal conditioning, portable and battery-operated equipment, current or voltage sensing interfaces, active filtering, and general analog buffers. Four amplifiers in one package can reduce board area when a design needs several channels. Applications requiring wider supply voltage, lower offset, lower noise, or different logic levels should verify those requirements against the complete manufacturer datasheet before production use. Designers should provide adequate input and output bypassing, verify stable operation with the intended load and feedback network, and confirm that the amplifier input common-mode range includes the full signal swing. Because the output-current figure is a headline feature rather than a complete load-capability specification, cable, headphone, and capacitive-load applications require careful review of the datasheet's output-stage limits. This product page consolidates verified distributor availability, pricing, environmental information, same-package alternatives, and practical selection guidance. It also distinguishes documented TS924ID facts from parameters that still require confirmation from the manufacturer datasheet, helping engineers narrow a replacement without making an unverified electrical assumption.

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.

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.

STMicroelectronics TS925IN is a four-circuit, general-purpose operational amplifier with rail-to-rail input and output capability, 4 MHz gain-bandwidth performance, standby mode, and an adjustable phantom-ground function. The device is packaged in a 16-DIP package measuring 0.300 inches, or 7.62 mm, across the row spacing. Its four amplifiers are intended for compact analog signal-conditioning systems where multiple buffered or amplified channels are required. An operational amplifier is an active analog semiconductor that uses high open-loop gain to amplify the difference between two input voltages. The TS925IN belongs to the general-purpose operational-amplifier family within the broader amplifier and analog IC hierarchy. Rail-to-rail input and output behavior allows the amplifier to operate across a substantial portion of its supply range, while the four-circuit arrangement consolidates four amplifier channels into one package. These characteristics make the device suitable for sensor interfaces, audio paths, instrumentation, and control-system signal chains. The main features of the TS925IN include four amplifier sections, a 4 MHz gain-bandwidth product, rail-to-rail operation, high output-current capability, standby mode, and an adjustable phantom-ground arrangement. Standby support can reduce active power consumption when signal handling is not required. The adjustable phantom-ground function can provide an internal reference point for noninverting amplifier configurations, which can simplify some gain-stage layouts and reduce the number of external reference components. The TS925IN is designed for general-purpose analog amplification rather than precision measurement or specialized high-voltage operation. Its four integrated channels can reduce board area compared with separate single or dual amplifier packages. Design engineers must still account for input common-mode range, output swing, supply voltage, stability, output-current demand, and the effect of the phantom-ground network when assigning signal levels. Because the accessible product records do not expose the complete electrical-limit table, exact slew rate, input bias current, output-current limit, and temperature limits should be confirmed in the manufacturer datasheet before release. Typical uses include four-channel sensor buffering, low-frequency audio amplification, industrial measurement interfaces, analog control loops, and general instrumentation. The 16-DIP package is appropriate for through-hole designs where insertion and inspection are important, although it occupies more PCB area than comparable surface-mount packages. The four-channel architecture is especially useful when four channels must be amplified consistently and nearby to the source or destination circuitry. A practical design choice is to keep feedback resistors close to the relevant amplifier pins, route high-impedance input traces away from switching nodes, and decouple each supply rail near the package. Confirm that the required output amplitude remains inside the usable output swing. For systems using standby or phantom ground, verify startup, shutdown, and settling behavior in the final signal-chain configuration rather than treating those features as isolated block-level functions. This page consolidates the verified product identity, package information, functional characteristics, sourcing workflow, replacement constraints, and application guidance for the TS925IN. It also distinguishes documented drop-in substitutes from differently packaged family members, helping engineers avoid assuming that a similar amplifier description guarantees footprint, pin, or electrical compatibility.

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

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.

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.

TS932IN - Dual 2.7V Rail-to-Rail Op Amp | STMicroelectronics

STMicroelectronics TS932IN is a dual, general-purpose operational amplifier designed for low-voltage systems operating from 2.7 V. The device uses rail-to-rail output stages and is specified to reach a 2.9 Vpp output swing with a 100 kΩ load when supplied from 3 V. It is packaged for through-hole assembly in an 8-pin Mini DIP package. The TS932IN combines two amplifier channels, low-voltage operation, and rail-to-rail output capability in one compact IC, making it useful for sensor conditioning, portable instrumentation, audio signal processing, and general analog signal-chain designs. An operational amplifier is an analog integrated circuit that compares two input voltages and amplifies the difference between them. It belongs to the amplifier IC hierarchy and supports feedback, filtering, buffering, level conversion, and closed-loop control functions. The TS932IN is a dual amplifier, so two independent signal-processing channels are available in one package. Its rail-to-rail output stage is particularly useful when the required output signal must approach the available supply-rail limits. The primary confirmed features of the TS932IN include operation down to 2.7 V, dual-circuit construction, rail-to-rail output behavior, and a 2.9 Vpp output swing at 3 V supply with a 100 kΩ load. This combination suits battery-powered and low-voltage embedded systems where headroom is limited. Because the output can operate close to the supply rails, designers can increase usable signal range without requiring a substantially higher supply voltage. In dual-signal applications, the TS932IN can process one channel as an active filter and the other as a buffer or gain stage. Symmetrical device construction helps simplify PCB planning in instrumentation, audio, communications, and industrial control products. Its through-hole Mini DIP package also remains convenient for prototyping, educational platforms, repair assemblies, and designs assembled with conventional through-hole insertion rather than fine-pitch surface-mount automation. Typical applications include sensor-signal conditioning, low-voltage audio processing, joystick and control interfaces, ADC input drivers, active filters, and general-purpose dual-channel analog amplification. In a sensor interface, one amplifier can scale or invert a sensor output while the second channel can provide buffering for an ADC. In an audio preamplifier, the rail-to-rail outputs can support low-amplitude signals when the system operates near the lower supply limit. A primary design consideration is output loading. The stated 2.9 Vpp swing applies to a 100 kΩ load, so heavier loads can reduce usable output range and alter distortion or stability behavior. PCB implementations should keep input and feedback paths short, place compensation or decoupling components close to their associated pins, and provide adequate ground return paths. Engineers should also review the complete manufacturer datasheet for input common-mode limits, output-current capability, noise, bandwidth, and stability requirements. This product overview combines the verified operating envelope, package identity, and application-focused engineering guidance with a side-by-side view of potential replacements. It also highlights where engineers must confirm pin compatibility, load conditions, and lifecycle requirements before approving a substitution or redesigning an existing 8-pin Mini DIP layout.

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.

The TS934IN is intended for low-voltage, low-power analog signal-conditioning circuits. An operational amplifier is an active analog integrated circuit that uses high open-loop gain to amplify small voltage differences. The TS934IN belongs to the operational-amplifier hierarchy of analog ICs, with rail-to-rail output swing and CMOS input characteristics. Its micropower operating current makes it suitable for battery-powered equipment, portable instruments, sensor interfaces, and low-power control systems where every microamp of supply demand affects battery life. The TS934 family provides rail-to-rail output swing, single-supply operation, CMOS inputs, ultra-low input bias current, and ESD protection. The TS934IN is identified as a general-purpose, two-circuit amplifier in a 14-DIP package. The 100 kHz gain-bandwidth product is appropriate for low-frequency buffering, amplification, filtering, and thresholding rather than high-speed signal processing. Its CMOS input stage is particularly useful when measuring high-impedance sources because input bias current is minimized. The TS934IN can operate from 2.7 V supplies, helping designers reduce the power requirements of portable systems. The manufacturer describes a 2.9 Vpp output swing with a 100 kΩ load when supplied from 2.7 V.

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 operates from a single supply of 2.5 V to 10 V and is packaged in an 8-pin SOIC. Each channel is designed for low-power signal conditioning and general-purpose analog measurements. An operational amplifier, or op amp, is a high-gain differential amplifier used to amplify, buffer, filter, or compare small voltage signals. In the signal-chain hierarchy, the TS942ID belongs to the operational-amplifier family within analog amplifier ICs and power-management systems. Its micropower operating current and rail-to-rail output behavior make it suitable for portable instrumentation, sensor interfaces, and low-voltage analog equipment. The TS942ID provides a supply-current consumption of 1.2 uA and an ultra-low input bias current of 1 pA. These characteristics reduce loading on high-impedance sensors and conserve energy in battery-operated systems. Its output swing is rail-to-rail, while single-supply operation extends to 10 V. The device also includes CMOS inputs, 2 kV ESD protection, and latch-up immunity for improved handling robustness. With a gain-bandwidth product of 10 kHz and a slew rate of 0.0045 V/us, the TS942ID favors precision and low-power operation over wideband performance. The 10 kHz bandwidth is suitable for slow sensor signals, ECG-scale physiological waveforms, precision current measurement, and low-frequency filtering. CMOS input stages support very low bias current, making the amplifier appropriate for high-source-impedance transducers where input loading must remain minimal. Typical uses include portable biomedical instrumentation, low-power sensor conditioning, battery-powered data acquisition, industrial process monitoring, and general-purpose buffering. Two independent channels can process complementary signals or provide simultaneous amplification. Because each channel can also be configured as a comparator-style element with suitable feedback, designers can use the same device for basic threshold and level-detection functions. The principal design consideration is bandwidth. The 10 kHz gain-bandwidth product limits high-gain signal bandwidth, so applications requiring faster edges or wider closed-loop bandwidth should account for the amplifier's finite slew rate. Input and output stability must also be evaluated with the source impedance, load capacitance, supply voltage, and selected feedback network.

The specified operating temperature range is -40 °C to +85 °C. An operational amplifier is an analog integrated circuit that amplifies the voltage difference between its inverting and non-inverting inputs. The TS94x family belongs to the operational amplifier, analog amplifier, and linear integrated-circuit hierarchy. Operational amplifiers are widely used as voltage followers, buffers, comparators, transimpedance amplifiers, and active analog filters. The TS942IN combines low supply current, single-rail operation, CMOS input characteristics, and rail-to-rail output swing in one low-power analog building block. The 1.2 µA micropower characteristic makes the TS942IN particularly suitable for battery-operated sensors, portable instruments, and low-energy monitoring systems. Its 2.5 V minimum supply voltage allows operation from a single low-voltage cell or regulated rail. Rail-to-rail output swing is valuable in low-voltage systems because it increases usable output range. The low input bias current reduces errors in source impedance-sensitive circuits and minimizes disturbance to high-impedance sensors. The TS942IN uses CMOS input circuitry and is intended for general-purpose low-power analog signal processing. Each amplifier can support common inverting, non-inverting, and voltage-following configurations. Because the output approaches the supply rails, careful load and feedback design remains necessary when the output must achieve accurate levels near either rail. Input common-mode range, output swing, gain-bandwidth behavior, and stability conditions should be taken directly from the manufacturer datasheet when selecting feedback networks. Typical uses include low-frequency sensor conditioning, portable instrumentation, medical monitoring, industrial threshold detection, and energy-efficient data acquisition. In battery-powered equipment, the low supply current reduces the continuous load imposed by the amplifier. In precision measurements, the low input bias current helps preserve the signal from sensors with high source impedance. The device is also useful when one package must provide two matched functional amplifier channels. Designers should verify the permitted input and output ranges at the selected supply voltage, account for input and output capacitance in feedback layouts, and avoid driving a load that exceeds the amplifier's recommended capability. A stable bypass capacitor close to the supply pins and short, direct routing for high-impedance inputs help preserve low-noise and low-power performance. This product page combines the manufacturer specifications, package information, sourcing guidance, functional alternatives, and practical circuit-level considerations for engineers evaluating the TS942IN. It is intended to accelerate part selection while keeping the critical design tradeoffs explicit: low power and low bias current versus the bandwidth, noise, and load capability required by a particular signal chain.

STMicroelectronics TS944ID is a four-channel general-purpose operational amplifier with rail-to-rail output, a 10 kHz gain-bandwidth product, and approximately 1.2 uA supply current per amplifier. The device is packaged in a 14-pin SOIC and operates from 2.5 V to 10 V across a -40°C to +85°C temperature range. Its four amplifiers make it suitable for compact, low-power analog signal-conditioning systems requiring several amplifier stages in one package. An operational amplifier is an analog integrated circuit that amplifies the voltage difference between its inverting and non-inverting inputs. The TS944ID belongs to the micropower operational-amplifier family within the broader linear-amplifier and signal-conditioning hierarchy. Rail-to-rail output allows the amplifier to approach its supply limits more closely than fixed-output amplifiers, improving output swing in low-voltage systems where signal headroom is limited. The principal benefits of the TS944ID are integration, low power consumption, and rail-to-rail operation. Four amplifiers in one 14-pin SOIC reduce component count and board area compared with four separate single or dual amplifier packages. The 10 kHz gain-bandwidth product is suitable for low-frequency signal conditioning, including sensor buffers, transducer amplification, and general feedback-control networks. Its approximately 1.2 uA supply current is especially useful in battery-powered instrumentation where continuous analog circuitry must consume little power. The TS944ID is designed for general-purpose analog applications rather than high-speed signal processing. Its modest 10 kHz gain-bandwidth product favors slowly changing signals, such as sensor outputs, voltage references, and control-loop error amplifiers. The 2.5 V to 10 V operating range supports low-voltage battery systems, portable instruments, industrial monitoring circuits, and embedded control platforms. The -40°C to +85°C range covers industrial and commercial environments where extended automotive qualification is not required. Typical uses include four-channel sensor acquisition, portable measurement systems, low-frequency active filters, analog signal conditioning, and embedded control interfaces. Using one quad device for similar low-frequency channels can simplify routing and reduce package count. However, all four channels share common supply pins, so they cannot use independent positive and negative supply voltages. Input common-mode and output-swing behavior should also be checked against the actual signal range. When laying out a TS944ID board, place each bypass capacitor close to the device supply pins and keep feedback components near their associated amplifier inputs and outputs. Use short, quiet input paths for sensor signals and provide adequate return paths to minimize ground coupling. Avoid using this micropower amplifier where wide bandwidth, high output-current capability, or precision offset and drift specifications are essential; a higher-bandwidth or more accurate amplifier family will usually provide a better margin. This page combines the verified TS944ID ordering information, package and electrical characteristics, application guidance, pinout, and strict same-footprint replacement analysis.

The TS944IN family emphasizes low power consumption and rail-to-rail output operation. Its 10 kHz gain-bandwidth product supports low-frequency amplification and filtering, while the 4.5 mV/us slew rate limits how quickly its output can change. Typical input bias current is 1 pA, which is useful when high-impedance sensors or sensing nodes must not be loaded heavily. The listed typical input offset voltage is 10 mV. STMicroelectronics describes the TS94x family as rail-to-rail micropower operational amplifiers for 2.5 V to 10 V operation. Four amplifiers in one package reduce board area and simplify design for systems that need several independent analog channels. The TS944IN is identified as a general-purpose amplifier and an obsolete catalog item, so lifecycle planning should account for its non-active status. Typical circuit roles include battery-powered sensor interfaces, low-frequency active filters, portable measurement systems, and general-purpose signal conditioning. Because the gain-bandwidth product is only 10 kHz, the device is better suited to slow analog signals than to high-speed waveform or video paths. Its rail-to-rail output also requires careful review of the input common-mode range for each operating condition. Design with the TS944IN using supply bypassing close to the power pins and verify each amplifier's feedback network, output load, input bias requirements, and stable operating gain.

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

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.
