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

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

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. This page combines verified manufacturer and distributor information with practical selection guidance, application analysis, honest data-gap notes, and same-family drop-in candidates.

TLV2462ID

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

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.

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.

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

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. This page combines verified product information, distributor availability, application guidance, and replacement constraints for practical engineering review.

TLV2543CN

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

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. It also separates verified facts from missing electrical details and explains the limits of the available drop-in alternative data, helping engineers plan a safe datasheet-verified design and procurement review.

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

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.

TLV2544QD

TLV2544QD - 12-Bit 4-Channel 200 kSPS ADC | Texas Instruments

The Texas Instruments TLV2544QD is a 12-bit, 4-channel, successive-approximation analog-to-digital converter with a maximum throughput of 200 kSPS, operating from a single 3 V to 5.5 V supply in a 16-pin SOIC (D) package. It is designed for low-power, low-speed data acquisition systems requiring four analog input channels and a serial output interface. The converter supports automatic power-down through both software and hardware control, helping reduce system power consumption when measurements are not continuously required. An analog-to-digital converter, or ADC, converts continuous analog voltages into digital values for processing by a microcontroller, DSP, or other digital controller. The TLV2544QD belongs to the SAR ADC family within the broader ADC and data-converter hierarchy. Its four input channels make it suitable for sensor monitoring, industrial control, instrumentation, and portable equipment where several analog measurements must be acquired with a compact serial interface. 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.

TLV2544QDRG4

TLV2544QDRG4 - 12-Bit 200kSPS 4-Ch SAR ADC | Texas Instruments

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.

TLV2545ID

TLV2545ID - 12-Bit 200 kSPS Serial ADC | Texas Instruments

Texas Instruments TLV2545ID is a 12-bit, single-channel, pseudo-differential successive-approximation analog-to-digital converter with a maximum conversion throughput of 200 kSPS, an integrated conversion clock, and serial output compatibility up to 10 MHz. 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

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.

TLV2545IDGKRG4

TLV2545IDGKRG4 - 12-Bit 200kSPS Serial ADC, MSOP-8 | Texas Instruments

The Texas Instruments TLV2545IDGKRG4 is a 12-bit, 200 kSPS, low-power, serial-interface analog-to-digital converter (ADC) using successive-approximation architecture in an 8-pin MSOP (DGK) PowerPAD package. It operates from a single 2.7 V to 5.5 V analog supply, supports a single pseudo-differential analog input, and includes a built-in conversion clock, an SPI/DSP-compatible serial interface up to 10 MHz, and an Auto-Power-Down mode that reduces current consumption to under 1 µA between conversions. An ADC (analog-to-digital converter) of this type is a precision data converter that quantifies an analog input voltage into a binary code. The TLV2545 belongs to the successive-approximation register (SAR) ADC family — a sub-class of general-purpose, low-latency converters — within the broader data-converter hierarchy of ADC/DAC ICs. SAR ADCs are favored when deterministic latency, simple serial interfacing, and low power dissipation are required, making them a common choice over delta-sigma ADCs for multiplexed or control-loop applications. Key features include ±1 LSB maximum INL and DNL, 72 dB SINAD, 85 dB SFDR at a 20 kHz input, 3.5 µs conversion time, Auto-Power-Down that activates at end-of-conversion, and TMS320-compatible serial output. The DGK MSOP-8 with PowerPAD provides a low thermal-resistance path, enabling reliable operation across the industrial -40 °C to +85 °C temperature range. The TLV2545 uses charge-redistribution SAR architecture with an internal sample-and-hold and a precision DAC. The integrated Auto-Power-Down dynamically reduces consumption to sub-microamp levels between conversions, allowing the part to serve battery-powered, event-driven, or polled systems without the overhead of an external analog switch. Typical applications include portable instrumentation and battery-powered sensors, industrial process control loops, multi-channel data-acquisition front-ends, digital signal processor (DSP) and microcontroller analog front ends, optical-networking monitoring, and touch-screen or panel-metering subsystems. When designing with this ADC, place the 1.5 nF CS capacitor and 10 µF bypass capacitor close to the supply pins, route the analog and digital grounds in a star or split-plane topology, and ensure the reference decoupling (REF decoupling capacitor) is short and noise-free. The internal oscillator and Auto-Power-Down mean no external clock is required for stand-alone operation.

TLV271CD

TLV271CD - 3 MHz, 16 V Low-Power RRO Op Amp | Texas Instruments

The Texas Instruments TLV271CD is a single, 16 V, 3 MHz CMOS operational amplifier with rail-to-rail output, 550 µA supply current per channel, and an 8-pin SOIC package. Its specified supply range is 2.7 V to 16 V, while its 3 MHz gain-bandwidth product and 2.4 V/µs slew rate support responsive signal conditioning. Designed as a low-power alternative to the TLC27x family, it suits systems that require output swing close to the supply rails without a higher-bandwidth amplifier. An operational amplifier is a voltage-controlled differential amplifier whose high open-loop gain makes closed-loop amplification practical when negative feedback defines the gain and bandwidth. The TLV271 belongs to the operational-amplifier, analog-amplifier, and semiconductor hierarchy. Its rail-to-rail output stage lets the output approach either supply rail under suitable load conditions, improving usable swing in low-voltage systems. The CMOS implementation also supports low power consumption, although total supply current depends on supply voltage, output activity, and load. The TLV27x family combines a 3 MHz bandwidth with 550 µA of supply current per channel and a 2.4 V/µs slew rate. According to the Texas Instruments manufacturer datasheet, the devices operate from 2.7 V to 16 V over an extended industrial temperature range of -40 °C to +125 °C. The verified search data identifies the TLV271CD as the commercial-grade 8-SOIC ordering variant. Its low quiescent current is valuable in battery-powered instrumentation, while its 3 MHz bandwidth is more useful than a micropower unity-gain-stable amplifier when moderate closed-loop bandwidth is required. The amplifier's architecture is suitable for voltage buffers, current-sensing interfaces, sensor amplification, and general-purpose analog filtering. Rail-to-rail output operation is especially relevant when the signal must use much of the available supply range. Designers should still check input common-mode range, output load, capacitive-load stability, and noise specifications in the manufacturer datasheet rather than assuming that rail-to-rail output also means rail-to-rail input. Stable feedback ratios and conservative capacitive loading help prevent oscillation. Typical uses include portable measurement systems, industrial sensor interfaces, low-voltage audio or communication blocks, active filters, and embedded control. The 3 MHz bandwidth allows higher closed-loop bandwidth than very-low-frequency precision amplifiers, while the 550 µA-per-channel current keeps demand modest. At low supply voltages, usable swing and input range become important design limits; at high frequencies, board parasitics and probe loading can materially alter observed performance. For implementation, bypass each supply pin with local decoupling and route feedback traces away from input and output nodes. Avoid placing large capacitive loads directly at the output unless the datasheet stability limits are checked. The main engineering trade-off is the combination of low power, moderate 3 MHz bandwidth, and single-supply rail-to-rail output: TLV271CD is not automatically interchangeable with op amps having different input architecture, noise, or compensation. This page consolidates the verified manufacturer specifications, distributor availability links, practical design notes, and explicitly qualified alternatives for engineers evaluating the TLV271CD in analog signal-chain designs.

The amplifier has rail-to-rail output operation, while the supplied data identifies a 39 nV/√Hz input noise voltage and an input bias current specification reaching 1 pA. These characteristics make it appropriate for sensor interfaces, analog measurement chains, buffering, and low-power embedded systems. Typical circuit use places the TLV271IP in non-inverting or inverting amplifier configurations, voltage followers, transimpedance front ends, and active filters. Because the output is rail-to-rail, the device can maximize usable signal range in low-voltage systems, although the exact output swing depends on load current and supply voltage. Its 3 MHz bandwidth enables higher-frequency signal paths than a slow precision amplifier, while the 550 µA supply current helps control power use in battery-powered or space-constrained equipment. The principal design consideration is supply and signal-headroom planning. The input common-mode range, output swing, load capability, noise performance, and stability requirements should be checked against the manufacturer datasheet for the selected supply and temperature conditions. Decoupling capacitors should be placed close to the power pins, and unused input pins must be handled according to the datasheet recommendations.

TLV272CD - Dual 3MHz 16V Rail-to-Rail Op Amp | Texas Instruments

The Texas Instruments TLV272CD is a dual, general-purpose operational amplifier with a 16 V maximum supply, 3 MHz gain-bandwidth product, 2.4 V/us slew rate, and rail-to-rail output in an 8-SOIC package. Each channel is designed for low-power signal conditioning while maintaining useful bandwidth for general-purpose analog systems. An operational amplifier is a high-gain analog building block used to amplify, buffer, compare, or integrate signals. The TLV272 belongs to the voltage-feedback operational-amplifier hierarchy and combines a wide supply range, low channel current, and rail-to-rail output capability. Rail-to-rail output allows the output to approach the positive or negative supply limit more closely than a conventional output stage, improving dynamic range in low-voltage systems. Verified device characteristics include 550 uA per channel, 3 MHz bandwidth, 2.4 V/us slew rate, 2.7 V to 16 V operating supply range, 39 nV/Hz input-noise density, and input bias current specified as low as 1 pA. The family is positioned for portable instrumentation, sensor interfaces, audio paths, and general signal conditioning where dual-channel operation reduces package count. The wide supply range supports both conventional 5 V analog systems and higher-voltage rails, while the 3 MHz bandwidth supports signals beyond audio-band precision-only applications. The 2.4 V/us slew rate helps preserve large-signal response, although the exact output amplitude, load, and frequency must be checked against the manufacturer datasheet before final sizing. Typical uses include low-power sensor interfaces, buffered analog measurements, audio voltage buffers, active filtering, and general dual-channel conditioning. The SOIC-8 package is suitable for conventional surface-mount PCB assembly, but pin numbering and electrical limits must be verified against the exact TLV272 datasheet. A key design consideration is that low power and moderate bandwidth do not eliminate the need for stable reference and feedback networks. Place bypass capacitors near the supply pins, use short feedback paths, and verify common-mode, output-swing, noise, and stability requirements against the application.

TLV272ID

TLV272ID - Dual 16V 3MHz R-R Op Amp | Texas Instruments

The Texas Instruments TLV272ID is a dual, 16 V, 3 MHz rail-to-rail output operational amplifier packaged in an 8-pin SOIC. It uses approximately 550 uA per channel and is specified for operation from 2.7 V to 16 V over a -40 C to +125 C temperature range. These headline values position it as a compact, low-power amplifier for general-purpose analog signal conditioning. An operational amplifier is an active analog component that amplifies the voltage difference between its differential inputs while using negative feedback to set closed-loop gain, filtering, or integration behavior. Within the hierarchy of integrated circuits, the TLV272 belongs to the operational-amplifier class, then to voltage-feedback amplifiers, analog ICs, and ultimately semiconductor signal-conditioning devices. Rail-to-rail output allows the output voltage to approach the supply limits at its rated operating conditions. Key verified characteristics include a 3 MHz gain-bandwidth product, dual-amplifier configuration, 550 uA supply current per channel, 16 V maximum supply rating, and rail-to-rail output operation. The 3 MHz bandwidth supports higher-frequency signal paths than very-low-bandwidth micropower amplifiers, while the 550 uA per-channel current supports battery-conscious designs. The -40 C to +125 C grade is suitable for industrial temperature requirements when the complete circuit is qualified for those conditions. The TLV272ID combines two independent amplifiers in one SOIC-8, reducing board area compared with two separate single-channel packages. Its operating characteristics are relevant for sensor interfaces, audio paths, filtering, and general voltage amplification. However, the provided web data does not specify input offset voltage, input bias current, noise density, output-current capability, or input common-mode range, so these values must be confirmed in the manufacturer datasheet before precision design. Typical uses include low-frequency audio amplification, buffered sensor outputs, active filters, and portable measurement circuits. When operating from a 2.7 V supply, engineers must confirm that output swing, input range, and load requirements remain acceptable at the selected signal amplitudes. The 16 V maximum rating does not by itself establish safe operation at every intermediate rail or temperature combination. The main PCB consideration is decoupling. Place input and output-conditioning components close to their associated pins, route feedback loops compactly, and provide stable supply bypassing. Stable operation also depends on the required common-mode and output ranges, load impedance, feedback topology, and output-current demand. This page combines verified manufacturer and distributor information with explicit data gaps, practical application guidance, and conservative sourcing. It is intended to speed engineering evaluation while avoiding unsupported claims about parameters not present in the retrieved records.
