TLV1562IDWRG4

TLV1562IDWRG4 - 10-Bit 2MSPS Quad ADC w/4-CH Mux | TI

The Texas Instruments TLV1562IDWRG4 is a 10-bit, 2 MSPS reconfigurable low-power analog-to-digital converter with a four-input analog multiplexer, dual sample-and-hold, parallel interface and power-down mode, housed in a 28-pin SOIC (DW) package. Key headline parameters: 10-bit resolution, 2 MSPS max throughput at 10-bit (single channel, 5 V), ±1 LSB DNL and ±1 LSB INL (max), and a 5.5 V absolute-maximum analog input. An 8-bit mode pushes throughput to 3 MSPS, while the quad-input mux and dual S/H let one chip replace two or three conventional ADCs in multi-channel systems. An ADC (analog-to-digital converter) is a mixed-signal integrated circuit that samples a continuous-time analog waveform and quantizes each sample into a binary code word. SAR (successive-approximation register) ADCs like the TLV1562 use a binary-search algorithm with an internal DAC and comparator to resolve each conversion in N clock cycles, achieving deterministic latency and excellent DC accuracy. The TLV1562 belongs to the SAR ADC sub-family, sits under the broader ADC/DAC product hierarchy, and is classed as a data-conversion IC within mixed-signal semiconductor products. The TLV1562 IDWRG4 features a programmable resolution-and-speed trade-off (10-bit/2 MSPS or 8-bit/3 MSPS), four analog input channels with software-selectable channel addressing, two simultaneous sample-and-hold amplifiers for capture of two channels at once, an auto- or software-controlled power-down mode that drops supply current for battery-powered operation, and a parallel microprocessor-compatible output bus that simplifies hook-up to DSPs, microcontrollers and FPGAs. Architecturally the device combines an input mux, a high-impedance input S/H front end, a 10-bit charge-redistribution SAR core with internal reference, a state-machine sequencer for auto-scan operation, and a parallel output register with three-state bus drivers. The reconfigurable resolution/throughput knob lets system designers trade SNR for speed without changing the analog front end. Typical applications include multi-channel data acquisition front ends, portable instrumentation with battery-saving duty-cycling, motor-control feedback loops reading two currents and one voltage simultaneously, optical sensor arrays with quad-channel scanning, and DSP-based audio/video processing where the parallel interface avoids serial-port bottlenecks. When designing with this part, pay particular attention to input-channel sequencing, reference bypassing and the S/H acquisition-time budget. Choosing software-mode power-down reduces IDD to a few hundred microamps between conversions - useful for handheld instruments where the ADC must wake, convert a burst and return to sleep.

TLV1572CD - 10-Bit 1.25 MSPS SAR ADC | Texas Instruments
TLV1572CD

TLV1572CD - 10-Bit 1.25 MSPS SAR ADC | Texas Instruments

Texas Instruments TLV1572CD is a 10-bit, single-channel successive-approximation analog-to-digital converter with a maximum sampling rate of 1.25 MSPS, a 2.7 V to 5.5 V single-supply range, and an 8-pin SOIC package. The converter accepts an unipolar analog input from 0 V to VCC and is designed for low-power signal-acquisition systems. Its specified power dissipation is 8 mW with a 3 V supply and 25 mW with a 5 V supply. Automatic power-down reduces the supply current to 10 μA whenever a conversion is not performed. An ADC converts a continuously varying analog voltage into a numeric value suitable for processing by a microcontroller, digital signal processor, programmable logic, or industrial controller. The TLV1572 belongs to the successive-approximation ADC, or SAR ADC, category within the broader analog-to-digital converter and data-converter hierarchy. This architecture is appropriate when an application needs compact conversion hardware, a moderate sampling rate, low power consumption, and a straightforward digital interface rather than the throughput of a pipeline ADC. The TLV1572 combines a 10-bit conversion resolution with a maximum throughput of 1.25 million samples per second. Its single 2.7 V to 5.5 V operating range allows operation from standard low-voltage and 5 V supply systems. Automatic power-down is particularly useful in intermittently sampled instruments because the converter can enter a low-current state between measurements. The available manufacturer information also identifies the device as a serial ADC with a very low-power operating mode. The serial interface reduces the number of signals required to transfer conversion results, helping conserve board area and connector pins. Digital data must still be clocked and framed correctly, so the host controller must match the converter's serial timing and logic levels. Because the ADC accepts a 0 V to VCC input range, signal conditioning is generally required when the source can be bipolar, noisy, slow-moving, or outside the converter's supply-referenced input limits. Typical uses include industrial process measurement, low-rate audio or vibration monitoring, battery-powered instruments, temperature-sensor acquisition, communications equipment, and compact embedded control systems. Selection should consider the required sampling rate, input bandwidth, noise performance, reference arrangement, power budget, and required conversion latency rather than resolution alone. A critical design consideration is to keep the analog input and reference network within the operating limits specified by the manufacturer. The input signal should be sampled through a suitable source impedance, and the PCB should minimize noise coupling into the sensitive analog node. Because detailed pin assignments, reference requirements, timing limits, and layout recommendations are not included in the supplied verified snippets, engineers should confirm them against the manufacturer datasheet before releasing a PCB. This product page consolidates the verified manufacturer and distributor information, distinguishes the converter's verified capabilities from unresolved datasheet details, and provides application-oriented design guidance without inventing unavailable pricing, pinout, or cross-reference information.

TLV1572ID

TLV1572ID - 10-Bit 1.25 MSPS Low-Power SAR ADC | TI

Texas Instruments TLV1572ID is a 10-bit, 1.25 MSPS, single-channel successive-approximation analog-to-digital converter designed for low-power data-acquisition systems. It operates from a single 2.7 V to 5.5 V supply, accepts an analog input from 0 V to VCC, and is housed in an 8-pin SOIC package. The converter provides 1 input channel, differential nonlinearity below ±1 LSB, integral nonlinearity below ±1 LSB, and 59 dB signal-to-noise and distortion ratio at a 500 kHz input frequency. A SAR ADC is a sampling data-converter category that compares the sampled input voltage against an internal DAC through a sequence of binary decisions. Unlike a flash or pipeline ADC, the SAR architecture generally requires less power while providing predictable conversion behavior. The TLV1572ID belongs to the broader ADC, data-converter, signal-processing IC, and semiconductor hierarchies, making it appropriate for embedded measurement, control, and industrial data-acquisition equipment. The principal performance features are the 1.25 MSPS maximum sampling rate, 10-bit resolution, single-ended input architecture, SPI-compatible serial interface, and automatic power-down capability. According to the manufacturer information, typical power consumption is 8 mW at a 3 V supply and 25 mW at a 5 V supply. These characteristics suit systems that need moderate conversion speed and compact implementation without the power and cost of a high-speed flash ADC. The TLV1572ID combines a sampling-and-hold input stage, internal 10-bit DAC, comparator, control logic, and serial output interface in an 8-pin SOIC. Automatic power-down helps reduce consumption when conversions are infrequent. The 59 dB SNR and distortion figure at 500 kHz provides a useful basis for evaluating signal-chain performance, while the stated DNL and INL limits characterize unipolar conversion linearity. Typical applications include industrial process monitoring, sensor signal acquisition, portable instrumentation, embedded control systems, battery-powered measurement equipment, and low-speed data loggers. Its single 2.7 V to 5.5 V supply range also allows it to operate directly from common 3 V and 5 V system rails. The 1.25 MSPS throughput provides sufficient speed for many control-loop and waveform-sampling tasks. Designers should verify the input range, reference behavior, digital-interface timing, and acquisition requirements against the manufacturer datasheet before finalizing a PCB. Input-source impedance, source settling, sampling capacitance, clock jitter, and digital return paths can materially affect practical conversion accuracy. Automatic power-down should also be accounted for when calculating wake-up latency and acquisition-cycle timing. This page consolidates verified manufacturer and distributor information, drop-in candidate analysis, application guidance, and design notes. It highlights the TLV1572ID's low-power SAR architecture and 1.25 MSPS throughput while clearly identifying the electrical details that still require datasheet confirmation.

Key features include the wide 2.7V to 16V supply range that tolerates 3.3V, 5V, and 12V automotive battery rails; rail-to-rail input and output that maximizes dynamic range in single-supply systems; and low 550µA/channel supply current for always-on battery-powered modules. The 3MHz bandwidth and 2.1V/µs slew rate support sensor signal conditioning and active filtering. Technically, the CMOS input stage provides high input impedance with picoamp-range input bias current, while the rail-to-rail class-AB output stage sources and sinks current with minimal distortion. The device is internally compensated for unity-gain stability and includes ESD protection on all pins for harsh automotive environments. Typical applications include automotive sensor signal conditioning, battery monitoring, motor-control current sensing, and active filters in engine control units. Rail-to-rail output swing maximizes ADC interface resolution. Design tip: decouple the supply with a 0.1µF ceramic capacitor placed close to the V+ pin, and keep output traces away from high-frequency digital lines to minimize coupling.

TLV2372ID - Dual 3MHz RRIO Op Amp | Texas Instruments
TLV2372ID

TLV2372ID - Dual 3MHz RRIO Op Amp | Texas Instruments

Texas Instruments TLV2372ID is a dual operational amplifier with rail-to-rail input and output capability, 3 MHz gain-bandwidth performance, and low 550 µA per-channel quiescent current in an 8-pin SOIC package. It operates from a 2.7 V to 16 V supply and provides a 2.4 V/µs slew rate. These characteristics position the TLV2372ID as a compact, low-power amplifier for portable, industrial, instrumentation, and signal-conditioning systems. An operational amplifier is an analog signal-processing IC that amplifies the voltage difference between its inverting and non-inverting inputs while providing high input impedance and low output impedance. The TLV2372 belongs to the operational-amplifier hierarchy within amplifier ICs and analog signal-chain devices. Its rail-to-rail input stage accepts signals near the positive and negative supply rails, while its rail-to-rail output stage can swing close to both rails under suitable load conditions. Key features include a 3 MHz gain-bandwidth product, 2.4 V/µs slew rate, 550 µA per-channel quiescent current, and operation from 2.7 V to 16 V. The dual configuration integrates two amplifiers into one 8-pin SOIC package, reducing board area when a design needs two gain stages, buffers, comparators, or differential signal-conditioning channels. Rail-to-rail operation is especially useful when the usable signal range is a large fraction of the available supply voltage. The low-power operating current supports battery-operated and energy-conscious systems, while the 3 MHz bandwidth provides more signal bandwidth than very-low-frequency micropower amplifiers. Designers should nevertheless check gain-bandwidth-dependent noise, slew-rate-driven large-signal error, output-capacitance stability, input common-mode range, and the actual output swing required by the load. The 8-pin SOIC package is also straightforward to assemble and inspect on through-hole prototype boards. Typical uses include low-voltage sensor conditioning, portable measurement equipment, audio and communication interface circuits, general-purpose buffering, and industrial control modules. Two channels can implement independent amplifier functions, or they can form an instrumentation-style differential stage when resistor networks and suitable common-mode behavior are considered. For each amplifier, connect input and output stability compensation according to the manufacturer datasheet, keep feedback paths short, and provide adequate bypassing near the supply pins. Avoid using the maximum listed bandwidth or slew rate as a guaranteed large-signal operating point without checking output swing and load-current limits. Decoupling capacitance and layout should follow the datasheet recommendations rather than generic values. This page combines the verified Texas Instruments product information, distributor listings, package details, and qualified same-family alternatives with practical selection guidance. It also separates confirmed parameters from unavailable values so engineers can cross-check the original TLV2372 documentation before making a drop-in decision.

TLV2372IP - 3MHz Dual RRIO Op Amp | Texas Instruments

The Texas Instruments TLV2372IP is a dual operational amplifier with rail-to-rail input and output capability, 3 MHz gain-bandwidth product, 2.4 V/µs slew rate, and 550 µA per channel supply current in an 8-pin PDIP package. The two amplifiers share a common supply range of 2.7 V to 16 V, making the device suitable for low-voltage industrial, instrumentation, sensor-interface, and signal-conditioning systems. Its CMOS inputs also support applications involving relatively high source impedances. An operational amplifier is an analog integrated circuit that amplifies the voltage difference between its inverting and non-inverting inputs. The TLV2372 belongs to the rail-to-rail input/output amplifier family, where the input common-mode range and output swing extend toward the supply rails. Within the broader semiconductor hierarchy, it is a dual-channel amplifier IC, a linear amplifier, and a general-purpose analog signal-conditioning component. The principal operating features include a 3 MHz bandwidth, 2.4 V/µs slew rate, 550 µA per channel supply current, 16 V maximum supply voltage, and 2.7 V minimum operating supply. Rail-to-rail input and output capability increases the usable signal range in systems whose operating points approach the positive or negative supply rail. The dual configuration provides two amplifiers in one 8-pin PDIP package, reducing board area compared with two separate single-channel devices. The TLV2372 uses CMOS input circuitry to suit high-impedance sensor interfaces. Its rail-to-rail input stage allows signals near either supply rail to be referenced without requiring the usual input common-mode restriction of older amplifier designs. The 3 MHz bandwidth is suitable for moderate-frequency signal processing, while the 2.4 V/µs slew rate provides comparatively rapid output transitions. Designers should still account for output-load capacitance and stability when driving longer cables, large capacitors, or capacitive sensor networks. Typical applications include low-power sensor conditioning, buffered instrumentation, transducer amplification, low-frequency active filters, audio preamplification, and general industrial signal processing. The dual topology is particularly useful when a design requires two closely related analog channels, such as differential measurement or gain stages that benefit from matched devices in the same package. A key design consideration is the 550 µA per channel supply current, which supports low-power operation but may still be significant in long-duration battery-powered equipment. Confirm the complete operating envelope, input offset voltage, output-current capability, noise characteristics, and absolute maximum ratings against the manufacturer datasheet before releasing a production design.

TLV2402ID

TLV2402ID - Dual 16V 5.5kHz RRIO Amplifier | Texas Instruments

Texas Instruments TLV2402ID is a dual, rail-to-rail input/output operational amplifier designed for low-voltage, low-power signal-conditioning systems. The verified device information identifies a 16 V maximum supply, 5.5 kHz gain-bandwidth product, two amplifier channels, and an 8-pin SOIC package. Its approximately 900 nA per channel supply-current capability makes the TLV2402ID suitable for battery-operated instrumentation where amplifier power must remain small. An operational amplifier is an analog integrated circuit that uses high-gain feedback to amplify the difference between two input voltages. The TLV2402 belongs to the broader operational-amplifier hierarchy, where it combines low quiescent current, rail-to-rail input and output operation, and reverse-battery protection. These characteristics place it between general-purpose precision amplifiers and micropower amplifiers designed for portable or energy-limited equipment. The verified family description identifies rail-to-rail input and output stages, wide supply-voltage capability, high common-mode rejection, and reverse-battery protection. Rail-to-rail input operation allows the input common-mode voltage to extend toward the supply rails, which is important when sensing signals across most of the available input range. Rail-to-rail output operation permits the output to approach either rail, improving usable output swing in low-voltage systems. Reverse-battery protection helps guard the amplifier against excessive current caused by improper battery installation. The 5.5 kHz gain-bandwidth product supports low-frequency signal amplification rather than high-speed waveform processing. Because the dual device provides two amplifiers in one package, both channels use the same supply and are intended to share common operating conditions. The approximately 900 nA per channel supply current is particularly important for battery-powered sensors, portable meters, and industrial monitoring devices that remain active for long periods. Typical applications include low-current sensor conditioning, portable measurement systems, battery-powered monitors, low-frequency filtering, and general-purpose analog signal processing. The 8-pin SOIC package can be assembled using conventional surface-mount production methods, while the dual-channel configuration reduces component count when a design requires two amplified signals or a gain stage plus an active filter. Designers should verify the complete electrical limits, common-mode range, output-swing behavior, stability requirements, and recommended external components in the manufacturer datasheet before releasing a production design. Because the verified information does not include the complete pin table, numeric common-mode-rejection values, input-offset specifications, or recommended external capacitor values, those details require confirmation from the authoritative TLV2402 documentation. This product record combines the verified Texas Instruments family description, distributor availability information, package identification, and design guidance. It also distinguishes the only supported same-footprint substitute found in the supplied cross-reference results and clearly identifies missing technical values that should be obtained from the manufacturer datasheet before precise circuit calculations are performed.

TLV2452AIDGKR

TLV2452AIDGKR - Dual 23uA RRIO Op Amp 220kHz | Texas Instruments

The Texas Instruments TLV2452AIDGKR is a dual, micropower rail-to-rail input/output (RRIO) operational amplifier in an 8-pin VSSOP (MSOP, DGK) package. It operates from 2.7V to 6V single supply (or ±1.35V to ±3V dual supplies) while consuming only 23uA per channel, with a 220kHz gain-bandwidth product and 0.11V/us slew rate. An operational amplifier is a high-gain differential-to-single-ended voltage amplifier and a fundamental building block of analog signal chains, used as buffers, active filters, comparators, and transimpedance amplifiers. Op amps sit within the linear IC hierarchy alongside comparators and voltage regulators; the TLV2452 belongs to the low-power (micropower) op amp family, which prioritizes ultra-low quiescent current for battery-operated systems. Key features include true rail-to-rail input common-mode range and rail-to-rail output swing to within 5mV of each rail at light loads, maximizing dynamic range in low-voltage designs. The A-grade version guarantees a maximum input offset voltage of 1.5mV, and CMOS inputs deliver 1pA typical input bias current for high-impedance sensor interfaces. Micropower 23uA-per-channel consumption directly extends battery life in always-on circuits. Fabricated on a CMOS process, the TLV2452 offers high input impedance with internal ESD protection and is specified from -40C to +125C. The dual-channel DGK-8 package saves board space versus two single amplifiers. According to the TLV245x datasheet (Rev. F), the family also includes shutdown variants for further power savings. Typical applications include battery monitoring, portable medical devices, photodiode amplification, and low-power active filters. Rail-to-rail output allows direct ADC interfacing without level shifting, and the low quiescent current suits IoT always-on sensing. Design tip: decouple the supply with a 0.1uF ceramic close to V+, and remember the 220kHz GBW limits closed-loop bandwidth - keep gains and filter frequencies modest to preserve phase margin.

TLV2452AIDGKR-Q1 - Dual 220kHz RRIO Op Amp, 23uA | TI

The Texas Instruments TLV2452AIDGKR-Q1 is an automotive-grade (AEC-Q100 qualified) dual micropower rail-to-rail input/output operational amplifier consuming only 23 uA per channel while delivering 220 kHz of gain-bandwidth product, supplied in an 8-pin VSSOP (DGK) package. It operates from a single 2.7 V to 6 V supply and is qualified for AEC-Q100 Grade 1 temperature (-40C to +125C). A rail-to-rail input/output operational amplifier is a type of precision op amp within the broader analog amplifier family whose input common-mode range and output voltage swing extend to within millivolts of both supply rails. This maximizes dynamic range in low-voltage, single-supply systems where signal levels approach the rails, a capability conventional op amps cannot provide. Key features include the industry-leading 23 uA/channel quiescent current (far below competitive devices at similar bandwidth), 220 kHz gain-bandwidth product, rail-to-rail input and output (RRIO) operation, and high output drive capability for its power class. The dual-channel integration saves board space and reduces BOM count in multi-channel signal chains. The TLV245x family achieves its performance point through a trimmed CMOS input stage combined with rail-to-rail output buffer architecture, providing stable gain-bandwidth across the full load range. The related TLV245x family also offers shutdown variants (TLV2453/2455) for further average-power reduction in duty-cycled systems. Typical automotive and industrial applications include battery monitoring and current sensing front ends, low-power sensor signal conditioning, portable instrumentation, and microcontroller ADC driver stages, where micropower consumption directly extends battery life and reduces self-heating. Design consideration: because gain-bandwidth is 220 kHz, keep closed-loop gains moderate for signal bandwidths above a few tens of kHz; with 23 uA supply current, output current drive is limited, so avoid heavy capacitive loads without isolation resistors.

TLV2462CD - Dual 6.4MHz RRIO Op Amp | Texas Instruments

The Texas Instruments TLV2462CD is a dual, low-power, rail-to-rail input/output operational amplifier with a 6.4 MHz gain-bandwidth product, 1.6 V/µs slew rate, and 80 mA output-drive capability in an 8-pin SOIC package. The device operates from a 2.7 V to 5.5 V supply and consumes approximately 500 µA per amplifier channel, making it suitable for portable and low-voltage systems. An operational amplifier is an analog signal-conditioning IC that provides high open-loop gain and negative feedback to amplify or buffer a voltage signal. The TLV2462 belongs to the RRIO operational-amplifier family, where RRIO denotes rail-to-rail input and rail-to-rail output. This places the device in the broader hierarchy of analog ICs, signal-chain ICs, amplifiers, and general-purpose amplifiers. The TLV2462CD provides rail-to-rail input capability for a wide common-mode range and rail-to-rail output swing for improved dynamic range in low-voltage systems. Its 6.4 MHz bandwidth supports higher-frequency signal processing than a conventional micropower amplifier, while the 1.6 V/µs slew rate improves large-signal response. Two amplifiers in one SOIC package reduce board area, and the 500 µA-per-channel supply current supports battery-conscious portable equipment. The dual architecture allows the two channels to perform related or independent functions. Common uses include signal buffering, gain stages, active filtering, sensor-interface amplification, and low-voltage logic-level signal conditioning. Because both amplifiers share a common supply in one package, designers must also account for shared supply current, thermal behavior, ground routing, and channel-to-channel interaction. Typical applications include portable instrumentation, battery-powered monitors, sensor conditioning, audio and communication interfaces, and portable test equipment. The 80 mA output-drive capability is useful when driving moderate loads, while the rail-to-rail output allows useful output voltage to be obtained near the positive and negative supply limits. When designing around the TLV2462CD, verify output-current demand and capacitive-load stability for the selected feedback network. Keep input and feedback traces short, maintain a low-impedance ground reference, and use decoupling close to the supply pins. The available verified material does not provide a complete order-specific pin table, so the pinout field is conservatively marked as unavailable rather than inferred.

TLV2462ID - 6.4 MHz Dual RRIO Op Amp | Texas Instruments

The Texas Instruments TLV2462ID is a dual, low-power, rail-to-rail input/output operational amplifier with a 6.4 MHz gain-bandwidth product, 1.6 V/µs slew rate, and operation from a single 2.7 V to 6 V supply in an 8-pin SOIC package. The TLV2462ID uses one amplifier per package and is designed for portable and general-purpose signal-conditioning applications requiring low power, wide bandwidth, and rail-to-rail operation. An operational amplifier, or op amp, is a voltage-controlled differential amplifier whose closed-loop behavior is determined primarily by external feedback components. The rail-to-rail input and output architecture places the TLV2462ID within the low-voltage power-management hierarchy as an analog signal-conditioning IC. It can operate on a single supply or with dual supplies, making it useful where signals occur near either supply rail. The TLV2462 family provides a 6.4 MHz gain-bandwidth product and 1.6 V/µs slew rate. Its 6 V maximum supply voltage supports low-voltage portable equipment, while the dual configuration reduces the number of packages required for stereo, differential, filtering, or instrumentation circuits. The rail-to-rail input common-mode range and rail-to-rail output capability help preserve signal headroom in compact systems. The TLV2462ID is offered in an 8-pin Small Outline Integrated Circuit package. The manufacturer describes the TLV2462 as a low-power dual operational amplifier intended for portable applications. Its combination of moderate speed, low-voltage operation, and dual-channel integration supports signal buffering, sensor conditioning, audio paths, and general-purpose analog processing when the system does not require a higher-speed or lower-noise precision amplifier. Typical applications include portable sensor interfaces, low-voltage audio signal conditioning, battery-powered measurement systems, active filters, and dual-rail or single-rail analog front ends. Designers should verify the complete electrical limits, common-mode behavior, output swing, shutdown configuration, stability requirements, and package details against the manufacturer datasheet before production release, particularly where input signals approach the supply rails. For low-noise or high-impedance sensor interfaces, compare the TLV2462ID against a precision low-noise amplifier because its 6.4 MHz bandwidth favors speed and general-purpose signal handling. Maintain adequate bypass capacitance near the supply pins and keep sensitive input and feedback paths short to minimize parasitic pickup, oscillation, and sensitivity to board-level interference. This product record combines the verified 6.4 MHz bandwidth, 1.6 V/µs slew rate, 6 V supply limit, 8-pin SOIC construction, operating-temperature range, pricing floor, and distributor availability with practical design guidance. It also distinguishes directly identified ordering variants from true drop-in alternatives and flags electrical parameters that still require confirmation from the manufacturer datasheet.

TLV2464CN - Quad 6V RRIO Op Amp | Texas Instruments

Texas Instruments TLV2464CN is a quad, 6 V, 6.4 MHz, rail-to-rail input and output operational amplifier packaged in a 14-pin PDIP. The four integrated amplifiers support low-power portable systems while providing approximately 500 µA of supply current per channel, 80 mA of output-drive capability, and a 6.4 MHz gain-bandwidth product. These specifications place the TLV2464CN in the low-power RRIO operational-amplifier category. A rail-to-rail input/output operational amplifier is a voltage-feedback amplifier whose input common-mode range and output swing can approach its supply rails. The TLV2464 family uses this capability to process signals near the limits of a low-voltage supply. Its role within the hierarchy is operational amplifier → rail-to-rail amplifier → low-power analog signal-conditioning IC, making it useful where amplifier channels must operate from limited supply voltage and headroom is constrained. Four amplifiers are integrated into one TLV2464CN package, reducing the number of packages required for multichannel analog designs. The 6.4 MHz gain-bandwidth product supports higher-frequency signal paths than a conventional low-power slow-slew-rate amplifier. Rail-to-rail input operation helps preserve signal integrity when common-mode input levels approach either supply rail, while rail-to-rail output operation increases usable output range at low supply voltages. The approximately 500 µA per-channel supply current and 80 mA output-drive capability provide a practical balance between power efficiency and drive capability. The 80 mA figure is relevant when the amplifier must charge external capacitive loads, drive ADC input networks, or operate with resistive loading. Actual usable bandwidth and output amplitude depend on closed-loop gain, load impedance, output voltage, and the device’s stability configuration. Typical uses include portable instrumentation, sensor-signal conditioning, battery-powered measurement systems, low-voltage analog front ends, communications equipment, and general-purpose buffering. Multiple channels can process related signals, such as sensor outputs, transducer feedback, analog monitoring nodes, or small-signal conditioning stages without requiring four separate amplifier packages. When designing around the TLV2464CN, verify the complete datasheet for input bias current, offset voltage, input protection behavior, output swing, and stability before fixing capacitor values or gain settings. Preserve the required bypass capacitance close to the supply pins and route feedback paths away from high-impedance input nodes. Consider whether the 6 V maximum supply and low-power operating point satisfy the system’s noise, slew-rate, and load requirements. This page consolidates verified manufacturer and distributor information, observed pricing, same-package alternatives, and practical design guidance for engineers evaluating the TLV2464CN. It also distinguishes documented electrical characteristics from values that require confirmation in the complete manufacturer datasheet.

TLV2464ID

TLV2464ID - Quad 6V 6.4MHz RRIO Op Amp | Texas Instruments

Texas Instruments TLV2464ID is a quad, 6 V, 6.4 MHz rail-to-rail input/output operational amplifier packaged in a 14-pin SOIC. The device provides four amplifier channels, 80 mA output-drive capability, and approximately 500 uA of supply current per channel. Its low-power design and rail-to-rail input/output architecture make it suitable for portable and low-voltage systems requiring four signal-conditioning channels in one package. An operational amplifier is an analog integrated circuit that amplifies the voltage difference between its two inputs. The TLV2464 belongs to the operational-amplifier hierarchy within analog ICs and combines high gain, common-mode input range, output swing capability, and output drive in a compact quad package. The rail-to-rail input stage supports signals approaching the supply rails, while the rail-to-rail output stage allows the output voltage to swing closer to both rails than a conventional non-RRIO amplifier. The TLV2464 family is specified for operation from a 6 V supply and provides a gain-bandwidth product of 6.4 MHz. Each channel is designed for low-power operation, with the verified family data indicating approximately 500 uA of supply current per channel. The listed 80 mA output-drive capability supports higher-capacitance loads and faster transitions than a lightly loaded general-purpose amplifier can provide. These features are relevant in filtering, buffering, level translation, and sensor-interface circuits. The input common-mode voltage range extends beyond the supply rails, increasing usable signal range in low-voltage systems. Rail-to-rail output swing improves signal utilization where conventional amplifier headroom would clip the waveform. Four independent channels reduce component count in multichannel analog front ends, although each amplifier still requires suitable bypassing and stable feedback compensation. The available TLV2464ID package is a surface-mount 14-pin SOIC rated from -40 C to +85 C. Typical uses include portable instrumentation, low-voltage sensor conditioning, active filters, audio and communication interfaces, control loops, and general-purpose buffering. The 6.4 MHz bandwidth is appropriate for moderate-frequency precision signal paths rather than high-speed video or RF applications. When all four channels do not need identical configurations, unused amplifier inputs should be tied to a defined potential close to the common-mode operating point rather than left floating. PCB design should place the supply bypass capacitor close to the device and preserve a low-impedance ground return. Decoupling requirements, stability criteria, input/output capacitance limits, and shutdown-pin details must be confirmed in the manufacturer datasheet because those values were not included in the supplied search data. Designers should also verify source and sink output-current limits against the actual load, especially when driving capacitive or nonlinear loads. This page consolidates the verified manufacturer and distributor information, separates known TLV2464ID characteristics from unavailable parameters, and documents same-brand drop-in options without presenting them as verified cross-brand substitutes. It also provides application guidance, comparison fields, and design cautions that help engineers evaluate this quad amplifier for an existing 14-pin SOIC design as of 2026-10-30.

TLV2472IP - Dual 6V 2.8MHz RRIO Op Amp | Texas Instruments

Texas Instruments TLV2472IP is a dual, low-power, rail-to-rail input/output CMOS operational amplifier with a 6 V maximum supply rating and 2.8 MHz gain-bandwidth product. It is supplied in an 8-pin PDIP package and provides two amplifiers per device, making it suitable for portable instrumentation, sensor conditioning, filtering, and low-voltage analog signal processing. An operational amplifier is an analog active device that amplifies the voltage difference between its non-inverting and inverting inputs. A rail-to-rail input/output amplifier can operate with input and output voltages approaching either supply rail, improving usable signal range in low-voltage systems. The TLV2472 belongs to the operational-amplifier hierarchy within analog and mixed-signal integrated circuits. Key characteristics include approximately 600 uA of supply current per channel, 1.4 V/us of slew rate, rail-to-rail input and output operation, and a 2.8 MHz gain-bandwidth product. These specifications position the device between very-low-power amplifiers and higher-bandwidth rail-to-rail amplifiers. Low input bias current of approximately 2.5 pA is especially useful when the amplifier must interface with high-impedance sensors. The TLV2472 family combines low quiescent current with comparatively high AC performance for micropower designs. Its CMOS input stage provides low bias current, while the rail-to-rail output stage offers improved output swing and usable drive for ADC front ends and low-capacitance nodes. The dual configuration reduces package count when two matched amplifier functions are required in the same analog subsystem. Typical applications include battery-powered sensor interfaces, portable medical and industrial measurement equipment, low-frequency active filters, transimpedance front ends, audio and communication signal conditioning, and buffering ADCs. Operation from low single-supply voltages is possible within the device's specified supply range, provided the input and output common-mode and absolute-maximum limits are respected. For design work, verify the operating supply range, output-current capability, and load stability under the selected gain configuration. Place bypass capacitance close to the supply pins and avoid driving capacitive loads without isolation or additional compensation. Because the device is a through-hole PDIP package, board layout should also account for lead spacing and mechanical clearance rather than treating it as a surface-mount equivalent. This page combines verified manufacturer and distributor information, package details, application guidance, and same-brand drop-in alternatives. It adds practical selection criteria and design cautions that are not presented as a substitute for the complete manufacturer datasheet.

TLV2541ID

TLV2541ID - 12-Bit 200 kSPS SAR ADC | Texas Instruments

Texas Instruments TLV2541ID is a 12-bit, 200 kSPS, single-channel successive-approximation ADC with serial output, SPI/DSP-compatible signaling, and operation from 2.7 V to 5.5 V in an 8-pin SOIC package. Its built-in conversion clock, automatic power-down capability, and TMS320-compatible interface support compact, low-power measurement systems. An ADC is an integrated circuit that converts an analog voltage into a digital code. The TLV2541 belongs to the successive-approximation ADC hierarchy, commonly abbreviated SAR ADC, and ultimately falls under data-converter and mixed-signal semiconductor categories. SAR converters are especially useful when moderate resolution, predictable conversion behavior, and a simple serial interface are more important than the very high throughput of a flash converter. Three principal specifications define the TLV2541: 12-bit resolution, a maximum conversion rate of 200 kSPS, and a single 2.7 V to 5.5 V supply. The converter also provides an integrated conversion clock. Verified performance data includes integral nonlinearity and differential nonlinearity of no more than ±1 LSB, signal-to-noise-and-distortion ratio of 72 dB, and spurious-free dynamic range of 85 dB at 20 kHz. The device uses a serial output architecture suitable for SPI-compatible and DSP-compatible signal processing. The interface is compatible with TMS320-class processors operating up to 10 MHz according to the manufacturer product description. Serial output reduces the number of signal lines required on a mixed-signal circuit board while allowing the converter to communicate directly with a microcontroller, digital signal processor, or serial communications controller. Typical uses include battery-powered industrial sensing, portable instrumentation, process-control measurement, low-speed data acquisition, and embedded systems that require analog monitoring without a parallel ADC bus. Its single-channel architecture is appropriate where one analog quantity must be sampled repeatedly. For multichannel systems, several converters can be used with analog multiplexing, provided settling time and acquisition requirements are reviewed carefully. The primary design consideration is ensuring that the analog input remains within the converter's valid range and that the serial interface timing matches the host processor. Decoupling, grounding, input-source impedance, and acquisition-time requirements should be evaluated against the manufacturer datasheet. Automatic power-down can reduce system consumption, but repeated wake-up intervals may affect effective sampling throughput. This page consolidates verified manufacturer and distributor information, drop-in same-family options, technical comparisons, and practical design guidance so engineers can assess the TLV2541ID without relying only on a distributor parameter table.

TLV2542ID - 12-Bit 200kSPS Dual SAR ADC | Texas Instruments

The Texas Instruments TLV2542ID is a 12-bit, 200 kSPS, dual-channel successive-approximation register analog-to-digital converter in an 8-pin SOIC package. It operates from a single 2.7 V to 5.5 V supply and provides serial output that is compatible with SPI and DSP interfaces operating up to 10 MHz. The device combines two analog input channels with a built-in conversion clock, chip select, serial clock, and serial data output for compact embedded measurement systems. An ADC is an analog-to-digital converter, a data-conversion IC that samples a continuously varying voltage and produces a corresponding numeric code. A successive-approximation-register, or SAR, ADC determines each conversion result through a sequence of internal comparisons. SAR ADCs are commonly used where predictable sampling, moderate resolution, low power, and compact serial interfaces are more important than very high conversion throughput. The TLV2542 belongs to the broader ADC data-converter and signal-processing semiconductor hierarchy. The TLV2542ID features 12-bit resolution, 140 kSPS or 200 kSPS maximum throughput options, and specified integral nonlinearity and differential nonlinearity of ±1 LSB maximum. Its signal-to-noise-plus-distortion ratio is specified at 72 dB, while the spurious-free dynamic range is 85 dB. The serial interface supports direct connection to microcontrollers, DSPs, and TMS320-compatible systems up to 10 MHz, reducing the need for external interface logic. The converter uses a single analog supply, with analog input and digital interface functions integrated into a small package. Automatic power-down helps reduce consumption when conversions are not continuously required. The dual-channel architecture is useful for monitoring two independent signals, while the 12-bit code provides approximately 4096 digital levels for each channel. Exact input-range, reference, and absolute-input details must be confirmed in the manufacturer datasheet before final design release. Typical applications include industrial process measurement, battery and power-system monitoring, portable instrumentation, sensor signal acquisition, and embedded DSP or MCU data logging. The serial interface reduces pin count compared with many parallel ADCs, while the dual input count allows one converter to serve two measurements. Designers should account for source impedance, sampling dynamics, reference accuracy, analog grounding, and serial-interface timing. A key implementation consideration is the relationship between analog signal conditioning and ADC accuracy. The front-end should present a low-impedance source, provide suitable filtering for the measurement bandwidth, and keep analog routing away from noisy digital clock and switching signals.

TLV2543CN - 12-Bit 11-Channel 66 kSPS ADC | Texas Instruments

The Texas Instruments TLV2543CN is a 12-bit, 11-channel, successive-approximation analog-to-digital converter with a 66 kSPS conversion rate, serial output, programmable power-down, MSB/LSB-first data transfer, and built-in self-test in a 20-pin PDIP package. The converter uses switched-capacitor, successive-approximation conversion and provides an inherent sample-and-hold function. Its 10 µs conversion time and 11-channel multiplexing make it suitable for compact industrial measurement systems that need several analog inputs without allocating a separate converter to every signal. An analog-to-digital converter is an ADC, a mixed-signal semiconductor that converts a continuously varying analog voltage into a numeric code for processing, measurement, logging, or control. The TLV2543 belongs to the successive-approximation ADC family and the broader data-converter and signal-processing IC hierarchy. Its 12-bit resolution provides 4,096 quantization levels, while its serial interface reduces the number of signal lines required when compared with a parallel-output ADC. The headline capabilities include 12-bit resolution, an 11-channel analog input multiplexer, and a maximum throughput of 66 kSPS. The device supports both MSB-first and LSB-first serial output formats, giving the host controller flexibility in clocking and data processing. Programmable power-down helps reduce consumption when measurements are intermittent, while three built-in self-test modes support diagnostic checks of the converter and its serial interface. Internally, the switched-capacitor SAR architecture compares the sampled input against a generated reference during successive conversion steps. An inherent sample-and-hold stage isolates the selected input during conversion, while the 11-to-1 multiplexer allows one converter core to service multiple analog sources. The manufacturer identifies the device as a 1 SAR ADC with 11 input channels and a serial control/data interface. Typical uses include industrial process monitoring, environmental sensing, instrumentation, laboratory measurement, and embedded control systems. An ADC can be used when the system must repeatedly select one of several sensors, convert the selected voltage, and transfer the resulting code over a compact serial bus. The TLV2543CN is particularly relevant where 12-bit resolution is sufficient but the number of available pins or PCB area is constrained. Designers should confirm the actual reference voltage, analog input range, acquisition timing, digital interface levels, and operating-temperature limits against the manufacturer datasheet before layout. Because this part is a multiplexed converter, source impedance, sampling charge, settling time, and protection-network capacitance can affect conversion accuracy. Decouple the supply and reference rails locally, keep analog routing away from fast digital signals, and account for the 10 µs conversion time when scheduling scans. This page consolidates the verified 12-bit, 66 kSPS, 11-channel, serial-output, power-down, and self-test characteristics with package information, application guidance, and a careful drop-in-replacement assessment.

TLV2543IN - 12-Bit 66 kSPS 11-Channel SAR ADC | Texas Instruments

Texas Instruments TLV2543IN is a 12-bit, 66 kSPS successive-approximation analog-to-digital converter with 11 analog input channels, serial output, programmable power-down, selectable MSB/LSB-first data transfer, and built-in self-test capability. It is supplied in a 20-pin PDIP package designated N. The converter combines a 10 µs conversion time with an inherent sample-and-hold function and three built-in self-test modes. An ADC is an analog-to-digital converter, a category of data-acquisition and signal-processing ICs that transforms a continuously varying voltage into a numeric code. A SAR ADC compares the sampled input against an internal DAC through a sequence of binary trials, producing one result at the end of each conversion. The TLV2543IN belongs to the switched-capacitor SAR ADC family and provides 11 channels plus serial control for compact, multiplexed measurement systems. The principal specifications verified for the TLV2543IN are its 12-bit resolution, 66 kSPS conversion rate, 11-channel input count, and 10 µs conversion time. Programmable power-down helps reduce activity when conversions are not required, while MSB/LSB-first selection provides interface flexibility. Three built-in self-test modes support device-level verification routines, and the inherent sample-and-hold architecture simplifies acquisition sequencing across multiple analog inputs. The device uses serial control and serial data transfer rather than a parallel data bus. Its control interface includes chip select, input/output clock, and data input signals, as described for the TLV2543 family. This interface keeps the pin count manageable in the 20-pin PDIP package and suits systems where the ADC shares a serial bus with other peripheral devices. Because the available source snippets do not state the reference-voltage range, input range, DNL, INL, or power specifications, those values require confirmation in the manufacturer datasheet before final circuit design. Typical applications include multichannel industrial process measurement, sensor multiplexing, laboratory data acquisition, battery or supply monitoring, and embedded control systems that require a compact serial ADC. The 11-channel arrangement is particularly useful when several analog quantities must be sampled with one converter. The 66 kSPS rate supports general-purpose acquisition rather than the very high sampling rates normally associated with waveform capture. Designers should verify the complete pinout, analog input range, reference requirements, settling behavior, and serial timing from the manufacturer datasheet before layout. Input filtering, source impedance, grounding, and decoupling also require application-specific review because those values are not present in the verified source excerpts. PCB compatibility must be confirmed by comparing the 20-pin PDIP footprint and signal functions rather than relying only on the device description. This page consolidates the verified 12-bit, 66 kSPS, 11-channel architecture, package information, interface options, and sourced availability information for TLV2543IN.

TLV2544CD - 12-Bit 200kSPS 4-Channel Serial ADC | Texas Instruments

The Texas Instruments TLV2544CD is a 12-bit, 200 kSPS, 4-channel serial-output ADC with a 16-pin SOIC package. It operates from a single 2.7 V to 5.5 V supply, uses a successive-approximation-register conversion architecture, and provides an 8-sample FIFO with automatic power-down control through software or hardware. An ADC is a data-acquisition IC that converts an analog voltage into a digital code for measurement, monitoring, or control. The TLV2544 belongs to the SAR ADC and serial-interface ADC hierarchy within analog-to-digital converters and data-converter ICs. Its 12-bit resolution provides 4096 discrete quantization levels, while four analog input channels let one converter service multiple sensors without requiring a separate ADC for each signal. The TLV2544CD supports input rates up to 200 kSPS and a stated conversion time of 3.86 microseconds. Its serial interface uses chip select, serial clock, serial data input, and serial data output signals, allowing the converter to communicate efficiently with microcontrollers and embedded processors. The integrated 8-entry FIFO helps buffer multiple conversions and reduces the frequency at which the host processor must retrieve results. Automatic power-down can be initiated through software or hardware, helping reduce power consumption in intermittent measurement systems. The 2.7 V to 5.5 V operating range supports both 3.3 V and 5 V system rails, although the selected external supply and reference implementation must remain within the device limits. Because the converter uses a serial output, board layout and signal-integrity practices remain important when clock rates increase. Typical uses include industrial process monitoring, portable data loggers, battery-powered sensor interfaces, consumer equipment, and embedded control systems. The four-channel architecture is especially useful when several slowly changing analog signals must be sampled through a shared host interface. The FIFO is useful when the processor occasionally needs time to perform other tasks between conversion bursts. Designers should verify the complete pin arrangement and electrical limits in the manufacturer datasheet before layout. Input-source impedance, reference stability, sampling behavior, digital-interface timing, and decoupling directly affect conversion accuracy. Place bypass capacitance close to the supply pins and keep analog and digital return paths controlled to minimize conversion and clock-related errors. This product page consolidates verified manufacturer and distributor information, package details, procurement data, and same-family drop-in candidates. It also distinguishes verified electrical facts from parameters that still require datasheet confirmation, helping engineers compare the TLV2544CD without relying on incomplete distributor summaries.

TLV2544ID - 12-Bit 200 kSPS 4-Channel SAR ADC | Texas Instruments

Texas Instruments TLV2544ID is a 12-bit, 200 kSPS, four-input successive-approximation-register analog-to-digital converter housed in a 16-pin SOIC package. It operates from a 2.7 V to 5.5 V single supply and provides a serial interface with chip select, serial clock, serial data input, and a three-state serial data output. Its conversion time is listed as 3.86 microseconds in the manufacturer datasheet. An ADC is an interface IC that converts continuously varying analog voltages into numerical values for processing by a microcontroller, DSP, or other digital controller. The TLV2544 belongs to the SAR ADC hierarchy, where an internal sample-and-hold circuit and successive comparison stages produce a digital result. This category is used when a system needs moderate resolution, predictable conversion speed, low power consumption, and a compact serial interface rather than a high-throughput parallel converter. The TLV2544ID combines 12-bit resolution with a maximum conversion rate of 200 kSPS and four analog input channels. Automatic power-down can be controlled in software or hardware, helping reduce current consumption when conversions are not continuous. The family also supports an eight-word FIFO and a four-channel multiplexing arrangement, allowing a compact converter to sample multiple sources sequentially. A single 2.7 V to 5.5 V supply simplifies integration with both 3.3 V and 5 V systems. The serial interface reduces the number of PCB traces and package pins required compared with a parallel ADC. Chip select permits sharing of the serial bus, while the three-state output can isolate devices on a common data line. Because the TLV2544 is a SAR ADC, sampling behavior, source impedance, acquisition time, reference stability, and digital-interface timing are central considerations in a complete measurement chain. Typical uses include industrial sensor acquisition, portable measurement instruments, battery-powered monitoring systems, process-control nodes, and embedded data acquisition. The four inputs are useful for monitoring thermistors, potentiometers, analog sensors, and mixed bipolar or unipolar signals when the selected input range and front-end circuitry support those sources. For reliable operation, keep analog and return paths short, bypass the supply close to the device, and confirm the source-impedance limits for the selected sampling rate. The digital interface should also use defined levels at all times because the three-state output must not contend with another driver. This product record combines manufacturer specifications, distributor availability information, same-family alternatives, interface guidance, and application-oriented design notes to provide practical engineering context beyond the basic ordering table.

The key operating characteristics include 12-bit resolution, 4 analog inputs, 200 kSPS maximum sampling performance, a 3 V to 5.5 V supply range, and a serial output architecture. The converter also includes automatic power-down, a low-power operating mode, and a conversion-clock and reference arrangement described in the family documentation. The 16-SOIC package is designed for conventional surface-mount PCB assembly and provides a practical footprint for compact analog front ends. The TLV2544QD is identified as an automotive-catalog device in the manufacturer product information. The available product listing identifies the TLV2544Q family as a 12-bit, 200 kSPS, low-power serial ADC family, while the target orderable part is the 4-channel SOIC version. Engineers should confirm the exact temperature range, reference details, input impedance, timing characteristics, and automotive qualification documentation against the current manufacturer datasheet before releasing a production design. Typical applications include industrial sensor interfaces, battery-powered measurement equipment, temperature and pressure monitoring, portable instrumentation, and low-speed motor or process-control systems. The four-channel architecture simplifies PCB routing by reducing the number of separate converter packages, while the serial interface helps limit pin count and support economical connection to a digital controller. Automatic power-down is particularly useful when the acquisition system operates intermittently. Designers should confirm analog input voltage limits, acquisition timing, reference stability, digital-interface levels, and the recommended input and reference decoupling network. PCB layout should keep the analog input traces short, separate sensitive analog routing from switching nodes, and provide a stable ground reference. The available verified information identifies the device as a 16-pin SOIC; a complete pin-level assignment was not present in the supplied data, so the pinout is intentionally not fabricated here.

The Texas Instruments TLV2544QDRG4 is a 12-bit, 200-kSPS, 4-channel, low-power, serial-output successive-approximation-register (SAR) analog-to-digital converter with AutoPower-Down, supplied in a 16-pin SOIC (D) package. It operates from a single 3 V to 5.5 V analog supply, integrates a built-in reference, conversion clock, and an 8× FIFO, and targets cost- and power-sensitive multi-channel data-acquisition systems. The Q-suffix designates the automotive temperature grade (-40 °C to +125 °C), and the G4 suffix denotes tape-and-reel packaging with Pb-free finish. A SAR ADC is a type of analog-to-digital converter that uses a binary-search algorithm against a precision DAC to resolve each input sample in N clock cycles, where N is the resolution in bits. SAR ADCs offer deterministic latency, no pipeline delay, excellent dynamic performance at moderate sample rates, and very low standby power - features that make them ideal for multiplexed sensor systems, motor-control feedback loops, and instrumentation where every conversion must complete in a known time. The TLV2544QDRG4 inherits all of these SAR traits and adds hardware (CS) and software (S/W) AutoPower-Down control, dropping supply current after each conversion to extend battery life in portable and remote installations. The device digitizes up to four single-ended inputs through an internal analog multiplexer at up to 200 kSPS aggregate throughput, and provides a 4-wire SPI/QSPI/MICROWIRE-compatible serial interface. AutoPower-Down reduces quiescent current to a few microamps between conversions, and differential non-linearity / integral non-linearity errors are specified at ±1.2 LSB maximum up to 125 °C. A signal-to-noise-plus-distortion ratio above the SNR figure cited for the family supports 12-bit effective resolution at the full sampling rate. Architecturally, the TLV2544QDRG4 combines a charge-distribution DAC array, a high-bandwidth input sample-and-hold, an internal 2.5 V reference (or external reference option via REFin), a digital conversion-control state machine, and the AutoPower-Down timing block. The reference and oscillator are fully internal, eliminating external components and shrinking BOM cost in space-constrained systems. Typical applications include automotive sensor interfaces, multi-channel industrial process control, battery-powered portable instrumentation, motor-speed/temperature monitoring, and any multi-channel data logger that needs deterministic low-latency 12-bit conversion. Compared with the TLV2548Q (which is the 8-channel pin-compatible cousin of the same family), the TLV2544QDRG4 trades two analog input channels for a smaller BOM footprint when only four channels are required. During design, keep analog and digital grounds tied to a single star point near the AGND pin, decouple AVDD with a 10 µF tantalum plus 0.1 µF ceramic combination within 5 mm of the pin, and observe the device's 200 kSPS maximum throughput budget when sequencing multi-channel conversions.

The device operates from a single 2.7 V to 5.5 V supply and is packaged in an 8-pin SOIC (D). It is suited to industrial measurement, sensor acquisition, DSP interface, and embedded control systems where a compact, low-power ADC with serial data output is required. An ADC is a data-acquisition semiconductor that converts an analog voltage into a numeric code for processing, storage, or transmission. The TLV2545 belongs to the ADC and DAC category, using the successive-approximation-register architecture to balance conversion speed, energy use, and implementation complexity. Its single pseudo-differential input arrangement supports measurement of one analog channel against a selectable reference-side connection, while the serial interface reduces the number of signals required when connecting the converter to a microcontroller, DSP, or programmable logic device. The TLV2545ID provides 12-bit conversion resolution, 200 kSPS maximum throughput, and operation from 2.7 V to 5.5 V. Its built-in conversion clock eliminates the need for an external timing source during ordinary sampling. Published family specifications also identify a 140 kSPS version within the TLV254x family, plus integrated and differential nonlinearity limits of ±1 LSB maximum, a signal-to-noise-plus-distortion ratio of 72 dB, and a spurious-free dynamic range of 85 dB. The serial output is described as SPI/DSP-compatible and compatible with TMS320 systems operating up to 10 MHz. The TLV2545ID is designed for low-power, mixed-signal systems. Its serial interface allows the analog input, digital interface, and supply references to be placed close to the sensor or signal source, which can reduce board area and simplify routing. The 8-pin SOIC package is also available in a more compact surface-mount footprint than a through-hole package, making the device practical for compact control and measurement equipment. Designers should still observe the datasheet limits for input range, reference voltage, acquisition time, clock timing, and supply sequencing. Typical uses include industrial sensor interfaces, battery-powered portable instruments, audio and control signal monitoring, and data acquisition front ends feeding a TMS320-compatible processor. The 200 kSPS throughput supports substantially faster sampling than many general-purpose low-speed ADCs, while the 12-bit code width provides 4096 quantization levels. In each application, the analog source, reference arrangement, and digital interface must be evaluated together because conversion accuracy depends on the complete signal chain, not only the converter itself. The principal design consideration is preserving the ADC's dynamic performance through careful reference and layout choices. Input and reference paths should be short, quiet, and appropriately decoupled according to the manufacturer datasheet, while the digital clock and serial data lines should be routed to limit coupling into the analog input. This page combines the verified manufacturer and distributor information with practical application guidance, alternative-selection constraints, and design notes that help distinguish the TLV2545ID from broader functional equivalents that are not necessarily pin-compatible.

TLV2545IDGKR - 12-Bit 200 kSPS Serial ADC | Texas Instruments

The Texas Instruments TLV2545IDGKR is a 12-bit, 200 kSPS successive-approximation analog-to-digital converter with a serial output, housed in an 8-pin VSSOP (DGK) package. Operating from a single 2.7 V to 5.5 V supply, the part features a 1-channel single-ended or pseudo-differential input, integrated conversion clock, autopower-down between conversions, and SPI/DSP-compatible serial interface that supports up to 10 MHz clock rates and TMS320 DSP connections. An ADC (analog-to-digital converter) is a data-conversion integrated circuit that samples a continuous analog voltage and produces a discrete digital code, and a successive-approximation-register (SAR) ADC does so by iteratively comparing the input against an internal DAC, achieving an excellent balance of speed, accuracy, and power consumption for precision low-frequency and audio-bandwidth signals. The TLV2545 belongs to the broader hierarchy of data-converter ICs, which sit within signal-chain and power-management semiconductor families. Key features of the TLV2545 include ±1 LSB maximum INL and DNL, 72 dB SINAD, and 85 dB SFDR at a 20 kHz input tone, along with a 3.5 µs typical conversion time and a flexible SCLK/FS-compatible serial interface. The autopower-down feature reduces current draw to a few microamps between conversions, which is critical for battery-powered and energy-harvesting applications where average load matters more than peak throughput. The architecture uses a charge-redistribution SAR core with an internal sample-and-hold and on-chip oscillator, eliminating the need for an external clock. The pseudo-differential input stage simplifies board layout by accepting ground-referenced signals without a negative rail, while the wide supply range permits direct interface to 3.3 V microcontrollers, 5 V DSPs, or low-voltage battery stacks. Typical applications include portable instrumentation, motor-control feedback loops, battery monitoring, sensor signal conditioning, point-of-load monitoring in industrial control, and audio-bandwidth digitization for consumer audio and telecommunications equipment. The 8-pin VSSOP footprint suits space-constrained designs. When designing with the TLV2545, place 100 nF decoupling close to the supply pin and follow layout practices that keep digital return currents away from the analog input. The SCLK clock rate must remain within the 10 MHz SPI specification, and CS falling-edge timing relative to SCLK should be reviewed against the TMS320 interface diagrams in the datasheet. This page synthesizes distributor pricing, drop-in same-package alternatives drawn from the same TI VSSOP-8 ADC family, and practical layout notes that go beyond what the manufacturer datasheet alone provides.
