TLV2371QDBVRQ1 Descripción general
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.

Aplicaciones típicas
TLV2371QDBVRQ1 es adecuado para 6 aplicacións: Automotive Sensor Signal Conditioning, Battery Monitoring and Management, Motor Control Current Sensing, Active Filters in Engine Control Units, ADC Interface Buffering, Portable and IoT Battery-Powered Devices.
Automotive Sensor Signal Conditioning
The TLV2371QDBVRQ1's AEC-Q100 qualification, -40C to +125C rating, and 2.7V-16V supply tolerance make it ideal for conditioning signals from automotive pressure, position, and temperature sensors. Its rail-to-rail input accepts signals near the ground rail common in resistor-bridge sensors, while the rail-to-rail output maximizes the input span of downstream 3.3V/5V ADCs. The 3MHz bandwidth and 2.1V/us slew rate accommodate kHz-range sensor signals with anti-alias filtering, and the 550uA quiescent current suits always-on modules powered from battery-cranked rails.
Recomendado
Battery Monitoring and Management
In 12V automotive battery monitoring, the TLV2371QDBVRQ1's 16V absolute supply rating covers normal charging voltages, and its CMOS inputs draw picoamp bias currents that prevent draining the sense node or corrupting high-impedance dividers. The rail-to-rail output swings to within millivolts of the rails, preserving measurement range across the full battery state-of-charge. At only 550uA per channel, it suits always-on current-shunt amplification ahead of ADCs such as the ADS131M08, while RRIO operation maintains accuracy at both low-cell and full-charge operating points.
Recomendado
Motor Control Current Sensing
The TLV2371QDBVRQ1 amplifies shunt-resistor voltages in motor-drive feedback loops for MCUs such as the TMS320F280041C-Q1. Its 3MHz gain bandwidth supports closed-loop current sensing with adequate phase margin, and the 2.1V/us slew rate tracks PWM-induced ripple at the shunt. The 16V supply survives gate-driver domain rails, while rail-to-rail output resolves near-zero current at low duty cycles. Pairing with isolated or precision current-sense amplifiers gives complete phase-current chains in automotive traction and auxiliary motor controllers.
Recomendado
Active Filters in Engine Control Units
ECU analog front ends use the TLV2371QDBVRQ1 as Sallen-Key or multiple-feedback active filters to reject alternator ripple and switching noise before ADC sampling. The 3MHz bandwidth supports corner frequencies up to tens of kHz with good Q accuracy, and RRIO behavior preserves headroom on battery-derived 5V rails. The 550uA/channel consumption keeps total ECU analog budget low across multiple filter stages, and AEC-Q100 qualification with -40C to +125C operation ensures stable filter characteristics across under-hood temperature extremes.
Recomendado
ADC Interface Buffering
SAR and delta-sigma ADCs need low-impedance drive; the TLV2371QDBVRQ1 buffers sensor or divider outputs before the ADC input. Its rail-to-rail output maximizes effective resolution on 3.3V supplies, while the 3MHz bandwidth settles signals within typical SAR acquisition windows at moderate sample rates. The CMOS input's picoamp bias current preserves accuracy with high-value divider networks, and unity-gain stability ensures no oscillation in the direct-buffer configuration common with devices like the ADS1115 or ADS1220.
Recomendado
Portable and IoT Battery-Powered Devices
With 550uA quiescent current per channel and operation down to 2.7V, the TLV2371QDBVRQ1 extends battery life in portable sensor nodes and IoT endpoints. The rail-to-rail input accepts signals near ground from photodiodes and microphones, and the rail-to-rail output drives comparators or ADCs directly without headroom loss. Its low-power 3MHz performance class fits kHz-bandwidth signal conditioning, and the tiny SOT-23-5 package conserves board area in space-constrained wearables, smart-home sensors, and battery-backed telemetry modules.

Notas de diseño
Decouple the V+ pin with a 0.1uF ceramic capacitor placed within 2-3mm of pin 5, plus a 1uF bulk capacitor per supply domain. In automotive environments add a series ferrite and TVS on upstream rails to survive load-dump transients - the TLV2371QDBVRQ1's 16V rating covers normal operation but not unclamped load dump.
The 3MHz bandwidth makes the output sensitive to capacitive loads above roughly 100pF; add a small series isolation resistor (10-50 ohm) when driving long cables or ADC input capacitance to preserve phase margin. Keep feedback traces short and route them away from CAN transceiver or clock lines to prevent coupled glitches.
Do not exceed the 16V absolute maximum supply even during automotive transients. For single-supply designs, remember the output cannot fully reach the negative rail beyond datasheet swing limits under load - verify headroom at minimum load current for zero-crossing sensor signals. Substitute only with same-pinout SOT-23-5 parts; verify temperature grade requirement before using industrial variants.
