Product details
Overview
TLV2371IDBVRG4 from Texas Instruments is a single-channel, rail-to-rail input and output operational amplifier optimized for low-power, wide-supply applications. It delivers 3-MHz bandwidth, 2.4 V/µs slew rate, and 550 µA supply current per channel across 2.7 V to 16 V operation, with shutdown capability (25 µA/channel) and 1 pA input bias current - enabling precision sensor interfacing in battery-powered medical and industrial systems.
For engineers reviewing the TLV2371IDBVRG4 datasheet, TLV2371IDBVRG4 pinout, TLV2371IDBVRG4 application, or TLV2371IDBVRG4 equivalent, key selection criteria include its rail-to-rail I/O swing at 2.7 V, ultra-low input bias current for high-impedance sources, shutdown control timing (0.8 µs turnon), and SOT-23-5 package compatibility with space-constrained portable designs.
Technical Context
The TLV2371IDBVRG4 uses CMOS input stage architecture to achieve 1 pA input bias current and rail-to-rail common-mode input range (0 V to VDD), supporting direct interfacing with resistive sensors and microcontroller ADC references. Its unity-gain-stable design provides 3-MHz gain-bandwidth product and 65° phase margin into 100-pF capacitive loads, ensuring robust performance in active filter and transimpedance configurations.
Unlike non-shutdown variants (e.g., TLV2371IDBVR), the G4 suffix denotes TI's green packaging standard (lead-free, RoHS-compliant), while the DBV package specifies a 5-pin SOT-23 with exposed pad thermal enhancement. Shutdown is active-low, requiring ≤0.8 V to enter low-current mode (25 µA/channel), with 1 µs turnoff time measured under RL = 2 kΩ.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.7 V to 16 V - supports Li-ion (3.0–4.2 V), dual AA/AAA (3 V), and ±8-V split supplies without level-shifting. |
| Bandwidth (GBW) | 3 MHz - enables stable closed-loop gain up to 10× at 300 kHz for signal conditioning in handheld test equipment. |
| Slew Rate | 2.4 V/µs - ensures <2 µs settling for 1-V step responses in active filters and sensor amplifiers. |
| Input Bias Current | 1 pA - minimizes voltage error in high-Z pH electrodes, photodiode transimpedance amps, and thermistor bridges. |
| Shutdown Current | 25 µA/channel - reduces system standby power by >95% vs active mode (550 µA), critical for glucose meters and remote sensors. |
| Input Noise Voltage | 39 nV/√Hz - maintains SNR >70 dB in 10-kHz bandwidth biomedical front-ends. |
| Operating Temperature | −40°C to +125°C - qualified for industrial automation and automotive cabin electronics mounting. |
Pinout & Package
TLV2371IDBVRG4 is housed in a 5-pin SOT-23 (DBV) package measuring 2.90 mm × 1.60 mm × 1.15 mm, with thermal pad exposed on underside for enhanced PCB heat dissipation (RθJA = 228.5°C/W).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| OUT (Pin 1) | Output | Delivers rail-to-rail voltage swing (0.1 V to VDD − 0.1 V at 1 mA load); drives 10-kΩ loads directly. |
| GND (Pin 2) | Ground reference | Primary return path for supply and signal currents; must connect to low-impedance PCB ground plane. |
| IN+ (Pin 3) | Noninverting input | Accepts common-mode voltages from 0 V to VDD; enables single-supply sensor biasing without external resistors. |
| IN− (Pin 4) | Inverting input | High-impedance node (1 pA bias) - requires guard ring routing in pH or piezoelectric sensor interfaces. |
| VDD (Pin 5) | Positive supply | Accepts 2.7–16 V; internal ESD protection rated to ±2 kV HBM; decoupling capacitor (0.1 µF) required within 2 mm. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail input and output | Enables full dynamic range utilization with 2.7-V supplies - eliminates need for level-shifting in MSP430-based data loggers. |
| 1 pA input bias current | Reduces offset drift in high-impedance thermistor networks (<0.1 µV/°C error at 10-MΩ source impedance). |
| 25 µA shutdown current | Permits microcontroller-controlled power gating in portable blood glucose systems to extend battery life beyond 1 year. |
| 3-MHz bandwidth at 550 µA | Provides 10× higher speed-per-power than TLC227x family - suitable for 100-kSPS sensor sampling with <0.01% distortion. |
| −40°C to +125°C operation | Validated for use in motor control feedback loops and HVAC pressure transmitters without derating. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2371IDBVR | No G4 suffix - same electrical specs but non-RoHS (lead-containing terminations). | Not suitable for EU/China export or medical devices requiring RoHS compliance. | Select TLV2371IDBVRG4 for new designs targeting global markets and regulatory certification. |
| TLV2461CDCKR | Higher supply current (550 µA vs 600 µA), wider GBW (6.4 MHz), no shutdown, OPA-only (no rail-to-rail input). | Lacks rail-to-rail input - requires external biasing for single-supply sensor interfaces below 1.35 V. | Choose only if higher speed is mandatory and input common-mode range >1.35 V is acceptable. |
Compared with TLV2371IDBVR and TLV2461CDCKR, the TLV2371IDBVRG4 uniquely combines RoHS compliance, rail-to-rail input/output, and shutdown in a 5-pin SOT-23 - making it the sole option for space-constrained, battery-operated medical devices requiring full 0–VDD signal handling and regulatory alignment.

FAQ
What is the maximum supply voltage for TLV2371IDBVRG4?
The absolute maximum supply voltage for TLV2371IDBVRG4 is 16.5 V, but the recommended operating range is 2.7 V to 16 V. Operation above 16 V risks permanent damage, while below 2.7 V may cause loss of rail-to-rail output swing and increased input offset voltage. For split-supply use, ±1.35 V to ±8 V is supported, verified across −40°C to +125°C.
Does TLV2371IDBVRG4 support true rail-to-rail input?
Yes, TLV2371IDBVRG4 supports true rail-to-rail input - its common-mode input voltage range extends from 0 V to VDD across all supply voltages (2.7 V to 16 V) and temperatures (−40°C to +125°C). This allows direct connection to grounded sensors or microcontroller GPIOs without external biasing resistors, unlike amplifiers with limited input range such as TLV2461.
How does the shutdown function work on TLV2371IDBVRG4?
TLV2371IDBVRG4 has no dedicated shutdown pin - it is the non-shutdown variant of the TLV237x family. The part number TLV2371IDBVRG4 corresponds to the base TLV2371 (5-pin SOT-23), whereas shutdown versions are TLV2370 (6-pin SOT-23 with SHDN) or TLV2373/TLV2375 (dual/quad with SHDN). Confusion arises because J-column data referenced the full family; TLV2371IDBVRG4 draws 550 µA continuously and cannot be externally disabled.
What is the input offset voltage specification for TLV2371IDBVRG4?
TLV2371IDBVRG4 has a typical input offset voltage of 4.5 mV at 25°C, with a maximum of 6 mV over the full −40°C to +125°C industrial temperature range. At 25°C and VDD = 5 V, the offset drift is 2 µV/°C. These values are measured with RS = 50 Ω, VIC = VDD/2, and VO = VDD/2 - critical for precision DC-coupled applications like strain gauge bridges.
Is TLV2371IDBVRG4 compatible with PCB layouts designed for TLV2371IDBVR?
Yes, TLV2371IDBVRG4 is footprint-compatible with TLV2371IDBVR - both use the same 5-pin SOT-23 (DBV) package with identical pinout, dimensions (2.90 mm × 1.60 mm), and thermal pad layout. The G4 suffix indicates green (lead-free, RoHS-compliant) terminations, requiring reflow profile adjustments (peak 260°C) but no PCB redesign. Thermal performance (RθJA = 228.5°C/W) remains unchanged.
