TLC272CDR - Dual 16V CMOS Op-Amp 2MHz SOIC-8 | Texas Instruments
The Texas Instruments TLC272CDR is a precision dual operational amplifier fabricated on TI silicon-gate LinCMOS technology, offering 2 MHz (typ 2.2 MHz) bandwidth, 3.6 V/us slew rate, and single-supply operation from 3 V to 16 V in an 8-pin SOIC package. An operational amplifier (op-amp) is a high-gain voltage amplifier with differential inputs, forming the foundational building block of the analog signal chain within the broader hierarchy of amplifier ICs, linear ICs, and semiconductors. Rail-to-rail style input flexibility on single-supply parts like the TLC272 lets designers amplify sensor signals that swing near ground without a negative supply, dramatically simplifying battery-powered and industrial designs. Key features include a maximum input offset voltage of 500 uV at 25 C with VDD = 5 V, extremely low offset drift of typically 0.1 uV/month (including the first 30 days), very high input impedance with low bias currents inherent to CMOS inputs, and a common-mode input range that extends to the negative rail (In to V-). These characteristics make it a cost-effective alternative to BiFET general-purpose amplifiers. The LinCMOS process provides input bias currents in the picoampere range, enabling direct interfacing with high-impedance sources such as pH probes, photodiodes, and piezoelectric sensors without external buffering. The dual amplifier in one SOIC-8 saves board area and improves channel matching in filter and instrumentation circuits. Typical applications include sensor signal conditioning, active filters, battery-powered portable instrumentation, and low-frequency data-acquisition front ends where single-supply, low-bias-current operation is required. Design consideration: keep source impedances moderate and use adequate supply bypassing; the CMOS input is sensitive to static, so observe ESD handling precautions.

TLE2022IDR - Dual Precision Low-Power Op Amp | Texas Instruments
The Texas Instruments TLE2022IDR is a dual precision, high-speed, low-power operational amplifier built on TI's Excalibur bipolar process, housed in an 8-pin SOIC (D) package and rated for the industrial -40C to +85C temperature range. It delivers 2 circuit channels with low offset voltage, high unity-gain bandwidth, and low power consumption typical of the Excalibur family, making it suitable for general-purpose precision signal conditioning from a single supply. The part is specified as a standard (general-purpose) amplifier in TI's amplifier portfolio. What is an operational amplifier (op amp)? An op amp is a high-gain DC-coupled electronic voltage amplifier with differential inputs and, typically, a single-ended output. It is one of the most ubiquitous building blocks in analog electronics, sitting below instrumentation amplifiers and active filters in the signal-chain hierarchy and above individual transistors in functional abstraction. Precision low-power single-supply op amps such as the TLE2022 family are optimized for systems that must operate from a single positive rail (often 3.3V or 5V) while still delivering DC accuracy and AC bandwidth close to what dual-supply parts achieve. Key features of the TLE2022IDR include two independent op-amp channels in a single SOIC-8 footprint, low power consumption characteristic of the Excalibur process, high-speed response relative to competing low-power op amps, unity-gain stability, and support for single-supply operation. The complementary bipolar process uses isolated vertical PNP transistors that improve input common-mode range and slew rate versus older designs, which is one reason the TLE2022 family remains popular as a successor to the OP21 in legacy designs. Typical applications include active filters, precision integrators, sample-and-hold front ends, transducer signal conditioning, and battery-powered instrumentation. The 8-pin SOIC footprint is industry standard, allowing easy hand prototyping and high-density SMT assembly on the same PCB land pattern used by countless alternative dual op amps. When designing with this device, observe the datasheet maximum supply rating and provide proper input common-mode biasing when used on a single supply; the lower rail of the input common-mode range may not extend all the way to ground. Decouple the supply pin close to the IC with at least 0.1 uF ceramic capacitance. A unity-gain stable part can be operated without compensation but should be kept clear of capacitive loads exceeding the datasheet's drive specification.

An operational amplifier is a high-gain differential-input voltage amplifier fundamental to analog signal conditioning, used for amplification, filtering, and buffering within the broader hierarchy of linear amplifiers and power management electronics. The TLV2371QDBVRQ1 belongs to the TLV237x-Q1 family of low-power rail-to-rail op amps within TI's general-purpose amplifier portfolio, purpose-built for automotive environments. 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. Pricing starts around $0.45 as of 2026-08-30.
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.
TLV2888IDGKR - 36V 14MHz Zero-Drift Dual Op Amp | TI
The Texas Instruments TLV2888IDGKR is a dual, zero-drift, CMOS precision operational amplifier designed for 36V systems and mux-friendly analog front ends. It combines a 14MHz gain-bandwidth product with a 40V/us slew rate and low 7.5nV/sqrtHz noise, making it one of the fastest zero-drift op amps available in an 8-VSSOP (DGK) package. The I-grade supports the -40C to +125C industrial temperature range, and the DGKR suffix indicates tape-and-reel packaging. A zero-drift operational amplifier uses auto-zero or chopper techniques to continuously cancel input offset voltage and thermal drift. In the system hierarchy: zero-drift op amp -> precision operational amplifier -> operational amplifier -> amplifier IC -> analog semiconductor. The TLV2888 belongs to the TLVx888 family (TLV888 single, TLV2888 dual, TLV4888 quad), optimized for applications needing both low DC error and wide signal bandwidth. Key features from the TI datasheet (TLVx888, Rev. B) include 3uV typical offset voltage, 0.01uV/C typical drift, and 150dB PSRR and 150dB CMRR. The input common-mode range extends to the negative rail and the output swings rail-to-rail, maximizing dynamic range on single supplies up to 36V. The mux-friendly input architecture minimizes charge-injection transients when inputs are switched, which is critical for multiplexed data-acquisition front ends feeding SAR or delta-sigma ADCs. The 14MHz bandwidth and 40V/us slew rate support fast sampled signals while preserving near-zero DC offset - a combination that distinguishes the TLV2888 from slower zero-drift amplifiers such as the OPA2187. Typical applications include multiplexed industrial data acquisition, high-precision sensor conditioning, motor-control current sensing, and servo or valve control loops where a 36V rail is available. Low offset and drift allow direct connection to precision ADCs like the ADS1220 without a separate auto-zero stage, and 150dB CMRR preserves accuracy across high common-mode voltages. Design tip: keep feedback resistors low enough to limit Johnson noise, decouple the supply pins close to the VSSOP-8 package, and avoid large capacitive loads on the output unless datasheet stability criteria are followed, or chopper ripple may increase. Pricing shown is indicative as of 2026-08-30.
TLV2888IDGKR-Q1 - Dual 36V 14MHz Zero-Drift Op Amp | TI
The Texas Instruments TLV2888IDGKR-Q1 is an automotive-qualified, dual-channel, zero-drift (chopper-stabilized) CMOS precision operational amplifier rated for 36V operation with a 14MHz gain bandwidth product, supplied in an 8-pin VSSOP (DGK) package. It belongs to the TLVx888 family (TLV888, TLV2888, TLV4888) of wide-bandwidth, low-noise, mux-friendly op amps. A zero-drift operational amplifier is a precision amplifier architecture that periodically self-corrects its input offset voltage using chopper stabilization or auto-zero techniques. Within the amplifier hierarchy, it sits under operational amplifiers, precision amplifiers, and analog signal-conditioning ICs, delivering DC accuracy that conventional CMOS or bipolar op amps cannot achieve without trimming. Key features include a maximum input offset voltage of only 15uV, a maximum offset drift of 0.05uV/C over the wide temperature range, rail-to-rail I/O operation, and a very high slew rate with fast settling time enabled by the wide 14MHz bandwidth. The mux-friendly input design minimizes channel-switching glitches when the amplifier follows an analog multiplexer, a common requirement in automotive battery-management and sensor-multiplexed front ends. Architecturally, the TLV2888 uses a zero-drift CMOS core that suppresses 1/f noise and offset through internal auto-correction, combining the DC precision of chopper amplifiers with the wide AC bandwidth of a fast CMOS output stage. This makes it effective both as a precision DC amplifier and as a high-speed signal-chain buffer. Typical applications include automotive battery management systems, current-sense amplification after a shunt (pair with INA-family monitors), multiplexed sensor front ends driving ADCs, and industrial precision signal conditioning. The 36V rating tolerates automotive load-dump-adjacent rail conditions. Design consideration: zero-drift amplifiers generate internal chopping ripple; follow the TI datasheet layout recommendations and verify settle time when driving switched-capacitor ADC inputs. Price references are as of 2026-08-29.
TLV3011AIDCKR - 5µA Open-Drain Comparator w/ 1.24V Ref | SC70-6 | TI
The Texas Instruments TLV3011AIDCKR is a micropower comparator with an integrated 1.242 V series voltage reference, packaged in a 6-pin SC-70 (DCK) footprint. It is an open-drain output variant of the TLV3011 family with a maximum quiescent current of 5 µA, input common-mode range that extends 200 mV beyond both supply rails, and single-supply operation from 1.8 V to 5.5 V. The on-chip voltage reference exhibits low 100 ppm/°C drift over temperature, making the part suitable for battery-monitoring and threshold-detection circuits where a stable reference is required without an external Zener or shunt. A comparator is an analog building block that compares two input voltages and produces a digital logic output indicating which one is larger. The TLV3011 family belongs to the open-drain comparator hierarchy, where the output transistor only sinks current and requires an external pull-up resistor to the desired logic rail. This contrasts with push-pull comparators like the TLV3012, which actively drive both high and low. Open-drain comparators are preferred when level-shifting is needed between logic domains, when wired-OR logic combining multiple comparator outputs is desired, or when the output must swing above VCC. Key features include 5 µA maximum quiescent current, 1.242 V reference with 100 ppm/°C drift, internal hysteresis for clean switching, and propagation delay in the microsecond range suitable for low-speed monitoring. The SC-70-6 package measures approximately 2.0 x 1.25 mm, allowing placement in space-constrained wearables, IoT sensor nodes, and portable battery-management boards. The wide input common-mode range (rail-to-rail minus 200 mV margin) supports monitoring of signals at or near the supply rails, which simplifies battery-voltage detection in single-cell Li-ion systems down to 3.0 V cut-off. Typical applications include battery voltage monitoring, window comparators for over-voltage/under-voltage detection, threshold detectors in portable medical devices, industrial sensor alarms, and simple relaxation oscillators. The internal reference enables a single-chip solution for generating a fixed threshold without adding external shunt regulators. When designing with this part, choose the external pull-up resistor on OUT to match the desired logic-rail rise time and current; 100 kΩ to 1 MΩ values are typical. Ensure the reference output capacitor (if used at REF pin) is sized to filter reference noise without slowing response. The open-drain output allows combining multiple TLV3011 outputs for wired-OR fault signalling in redundant-supply monitor circuits.

TLV316QDBVRQ1 - 10MHz RRIO Op Amp, AEC-Q100, SOT-23-5 | TI
The Texas Instruments TLV316QDBVRQ1 is an automotive-grade, single-channel, 10-MHz, rail-to-rail input/output (RRIO) CMOS operational amplifier in a 5-pin SOT-23 (DBV) package. It operates from 1.8 V to 5.5 V single supply, delivers 10 MHz gain-bandwidth product, 400 µA/channel quiescent current, and 12 nV/√Hz input voltage noise density at 1 kHz, making it a strong general-purpose low-voltage op amp for cost-sensitive signal chains. An operational amplifier (op amp) is a high-gain DC-coupled differential amplifier that uses external feedback to set its closed-loop behavior - gain, bandwidth, input impedance, and output impedance. Op amps form the fundamental building blocks of analog signal conditioning: inverting/non-inverting amplifiers, active filters, integrators, comparators, transimpedance amplifiers, and current/voltage buffers. Within the broader signal-chain taxonomy, general-purpose CMOS op amps sit between low-power chopper/zero-drink amplifiers and high-speed current-feedback op amps, optimized for portable, battery-powered, and automotive sensor-interface applications. Key features of the TLV316QDBVRQ1 include rail-to-rail input common-mode range that includes both supply rails, rail-to-rail output swing within tens of millivolts of either rail, 1.8 V minimum supply enabling direct Li-ion/cell operation, 400 µA typical quiescent current per channel, and 12 nV/√Hz voltage noise density at 1 kHz. AEC-Q100 Grade 1 qualification (-40 °C to +125 °C ambient), HBM ESD Class 3A, and CDM ESD Class C5 ratings make it suitable for under-hood and cabin automotive modules. Internally the device uses a CMOS input stage that supports true rail-to-rail common-mode operation without the crossover-distortion artifacts of legacy bipolar RRIO parts. The 10-MHz gain-bandwidth product combined with 6 V/µs typical slew rate provides sufficient speed for moderate-bandwidth sensor conditioning, audio pre-amplification, and active filter stages at audio frequencies. Typical applications include automotive sensor signal conditioning (current-shunt monitors, thermistor bridges, pressure/temperature transducers), body and chassis ECUs, infotainment audio pre-amplifiers, low-side/battery current sensing, and portable/mobile precision buffers. The wide supply range also supports industrial 3.3 V and 5 V PLC analog input modules. When designing with this op amp, place a 0.1 µF decoupling capacitor within a few millimeters of the supply pin, use a feedback network that keeps total gain above the minimum stable gain of 1 V/V (unity), and observe the input common-mode range - although RRIO, the input stage shifts distortion performance near the rails, so biasing the input mid-supply preserves linearity. This page synthesizes distributor pricing, drop-in pin-compatible alternatives, and practical PCB design notes that go beyond the manufacturer datasheet to accelerate automotive and industrial analog front-end design decisions.
TLV3201AIDCKR - 40ns microPOWER Comparator, SC-70-5 | Texas Instruments
The Texas Instruments TLV3201AIDCKR is a single-channel, 40 ns microPOWER push-pull comparator in a 5-pin SC-70 (DCK) package, drawing only 40 µA of quiescent current. It features rail-to-rail input common-mode range, 1 mV typical input offset voltage, and a wide 2.7 V to 5.5 V single-supply operating range. The push-pull CMOS output stage delivers large output drive current without requiring an external pull-up resistor. A comparator is an analog circuit building block that compares two input voltages and forces its output to one of two logic states based on which input is larger. The TLV3201 belongs to the high-speed, low-power comparator sub-category of analog comparators, which sits within amplifiers/comparators -> analog ICs -> signal conditioning -> power management. This combination of 40 ns propagation delay and 40 µA supply current places the part at the high-speed / low-power boundary, making it attractive for battery-powered systems that also need fast overvoltage detection or threshold-crossing response. Key features include 40 ns propagation delay (typical), 40 µA quiescent current, rail-to-rail input common-mode range that can swing 200 mV below the negative rail, push-pull CMOS output capable of driving typical CMOS or TTL loads directly, internal hysteresis for clean switching in noisy environments, and an industrial -40 °C to +125 °C operating temperature range. The small SC-70-5 (2.0 × 2.1 mm) footprint enables compact designs for space-constrained applications. The TLV3201 is built on a CMOS process with a precision input stage that achieves 1 mV input offset while maintaining microamp quiescent current. The push-pull output eliminates the static current draw of an open-drain pull-up resistor, improving efficiency in battery-powered systems. The wide 2.7 V to 5.5 V supply range supports both 3.3 V and 5 V rails commonly used in industrial and consumer designs. Typical applications include battery management threshold detection, zero-crossing detectors for line-powered systems, oscillator circuits, window comparators, IR receiver signal conditioning, and general-purpose analog monitoring. The part is particularly well suited for portable and handheld equipment where the 40 µA supply current extends battery life while the 40 ns speed supports fast fault response. When designing with this comparator, account for input source impedance and bias current to limit offset-induced errors. For high-speed switching above 100 kHz, add local supply decoupling (0.1 µF ceramic in parallel with 1 µF bulk) within 5 mm of the VCC pin. The internal 6 mV hysteresis is sufficient for most noisy environments, but for very slow-moving inputs add external positive feedback to widen the hysteresis band. This page synthesizes distributor pricing, drop-in alternatives in the same SC-70-5 footprint, and practical design notes not found in the manufacturer datasheet.
TLV3701IDBVR - Nanopower Push-Pull Comparator | Texas Instruments
The Texas Instruments TLV3701IDBVR is a single-channel nanopower push-pull comparator in a 5-pin SOT-23 (DBV) package, drawing only 560 nA per channel of supply current. It operates from a 2.7 V to 16 V single supply and features an input common-mode range that exceeds both supply rails by 200 mV, with 18 V reverse-battery protection on the inputs. A comparator is an analog circuit that compares two input voltages and produces a digital output indicating which is larger; the push-pull CMOS output stage of the TLV3701 drives a rail-to-rail logic level without an external pull-up resistor. As a member of the comparator family within the broader signal-chain IC hierarchy, the TLV3701 belongs to the nanopower class, designed specifically for ultra-low quiescent current applications where battery life is paramount. Key features include 560 nA quiescent current per channel, a typical propagation delay of 22 microseconds at 5 V, 18 V input tolerance with reverse-battery protection, and CMOS push-pull output capable of driving standard CMOS or TTL loads directly. The device also integrates ESD protection cells on the pins exceeding 2 kV HBM, and the SOT-23-5 package occupies only 2.9 mm x 1.6 mm of board area, enabling high-density PCB layouts. Technically, the TLV3701 uses a CMOS architecture with an internal bandgap reference for the threshold, an input stage tolerant of rail-to-rail common-mode swings, and a symmetrical push-pull output driver. The slow 22 us propagation delay is the deliberate trade-off for achieving sub-microamp quiescent current; the part is not suited for high-speed signal conditioning but is engineered for monitoring tasks that change state infrequently. Typical applications include battery voltage monitoring in wireless sensor nodes, low-frequency threshold detection in portable medical devices, micropower window comparators, system reset supervision, and battery-powered security sensors. The wide 2.7-16 V supply range also makes it suitable for industrial 24 V (nominal) line monitoring when divided down by external resistors. When designing with this device, place a 0.1 uF bypass capacitor within 2 mm of the VCC pin and minimize input trace lengths to reduce parasitic coupling. The slow propagation means it should not be used in fast closed-loop control, but for monitoring battery voltage or generating wake-up signals in IoT devices, the 560 nA supply current is the headline advantage. This page synthesizes distributor pricing, drop-in alternatives, and practical design notes not found on the manufacturer product page, giving engineers an actionable comparison set for nanopower comparator selection.

The Texas Instruments TLV376IDBVR is a 5.5-MHz, 100-µV offset, 8-nV/√Hz noise, 815-µA precision operational amplifier in a 5-pin SOT-23 package, built on TI's e-trim technology. It features rail-to-rail input and rail-to-rail output (RRIO) operation, 5.5-MHz gain-bandwidth product, 2-V/µs slew rate, and 1.2-mA quiescent current. The device operates from a single supply of 2.25 V to 5.5 V (or ±1.125 V to ±2.75 V). An operational amplifier (op amp) is a high-gain DC-coupled electronic voltage amplifier with differential inputs and a single-ended output, used as the fundamental building block of analog signal conditioning. Within the broader taxonomy, op amps belong to linear integrated circuits -> amplifiers -> analog ICs -> semiconductors. The TLV376 specifically sits in the precision low-noise sub-category, optimized for dc accuracy plus moderate-speed ac performance - bridging the gap between zero-drift instrumentation amps and general-purpose CMOS op amps. Key features include 125-µV maximum input offset voltage, 8-nV/√Hz input voltage noise density at 1 kHz, 5.5-MHz unity-gain bandwidth, 2-V/µs slew rate, and rail-to-rail input and output swing. The e-trim trim architecture achieves dc precision comparable to chopper-stabilized parts without the chopping artifacts, while keeping the noise floor low enough for transducer and audio front-end designs. The TLV376 uses a CMOS input stage with e-trim digital offset correction performed at wafer probe, plus a bipolar-style class-AB output stage capable of driving 1 kΩ loads to within 50 mV of either rail. The combined architecture yields a low-power precision op amp suitable for battery-powered instrumentation. Typical applications include battery-powered instrumentation, sensor signal conditioning (thermocouple, RTD, bridge amplifiers), handheld test equipment, audio front-ends, and active filters. Its low quiescent current makes it attractive for always-on IoT sensor nodes. When designing with the TLV376, observe the input common-mode range: although specified rail-to-rail, linearity degrades within 1 V of either rail - keep inputs in the linear region (0 to V+ minus 1 V) for best THD. Decouple V+ with a 0.1-µF ceramic bypass capacitor placed within 5 mm of the supply pin. This page synthesizes distributor pricing, drop-in alternative listings, and practical design notes not found in the standalone datasheet, helping engineers evaluate the TLV376IDBVR against competing precision op amps.

Per TI datasheet, the device is stable with capacitive loads up to 100 pF. Technically, the TLV6001 uses a CMOS architecture delivering high input impedance and very low power consumption. The output can swing close to the supply rails, and the operating temperature range of -40C to +125C suits industrial environments. The compact SOT-23-5 footprint supports dense PCB layouts. Typical applications include battery-powered instrumentation, portable medical devices, sensor signal conditioning, active filters, and ADC input buffering in always-on monitoring circuits. Design tip: decouple with a 0.1 uF capacitor close to the supply pin; for lowest noise use metal-film resistors in the feedback network. As of 2026-08-30, distributor pricing starts near $0.09 (LCSC) to $0.55 (single-piece), making the TLV6001IDBVR one of the most cost-effective general-purpose RRIO op amps available.
TLV7031DBVR - Nanopower Comparator, 5nA, 1.6V-5.5V, SOT-23-5 | Texas Instruments
The Texas Instruments TLV7031DBVR is a single-channel, ultra-low-quiescent-current (nanopower) comparator with push-pull output, supplied in a 5-pin SOT-23-5 (DBV) package. It operates from a 1.6 V to 5.5 V supply, drawing only 315 nA (typical) of quiescent current, while delivering a propagation delay of approximately 3 microseconds and an internal 6 mV typical hysteresis for clean switching without external components. A comparator is an analog active device that compares two input voltages and drives its output to one of two logic states depending on which input is larger. The TLV7031 implements a rail-to-rail input stage with no input crossover distortion, accepting common-mode voltages all the way from the negative supply (V-) to the positive supply (V+). Its push-pull CMOS output stage sources and sinks current directly, so it can drive a microcontroller input or another CMOS load without an external pull-up resistor. Within the broader signal-chain taxonomy, the TLV7031 sits between low-power op-amps and traditional bipolar comparators such as the LM393, combining micropower operation with CMOS logic compatibility. Key features include 315 nA typical quiescent current, 1.6 V to 5.5 V supply range, ±0.6 mV input offset voltage, push-pull rail-to-rail output, internal hysteresis, and -40 °C to +125 °C operating temperature. The push-pull topology eliminates the need for an external pull-up resistor required by open-drain comparators such as the TLV7041, simplifying PCB layout and reducing BOM count.
