Product details
Overview
TLV2371IDBVTG4 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 gain-bandwidth, 2.4 V/µs slew rate, 550 µA supply current per channel, and operates from 2.7 V to 16 V - enabling use in Li-ion-powered handheld test equipment and portable medical sensors.
For engineers reviewing the TLV2371IDBVTG4 datasheet, TLV2371IDBVTG4 pinout, TLV2371IDBVTG4 application, or TLV2371IDBVTG4 equivalent, key selection criteria include shutdown capability (25 µA/channel), ultra-low input bias current (1 pA), rail-to-rail swing at 2.7 V, and SOT-23-5 packaging for space-constrained designs.
Technical Context
The TLV2371IDBVTG4 employs CMOS input stage architecture enabling 1 pA input bias current and rail-to-rail common-mode input range (0 V to VDD). Its unity-gain-stable design supports capacitive loads up to 100 pF with 65° phase margin, and features active-low shutdown control with 0.8 µs turnon/1 µs turnoff timing.
It achieves 39 nV/√Hz input voltage noise at 1 kHz and maintains 50 dB minimum CMRR over full industrial temperature range (−40°C to +125°C) while operating on supplies as low as 2.7 V - making it suitable for high-impedance sensor front-ends in battery-powered systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.7 V to 16 V - supports single-cell Li-ion (3.0–4.2 V), dual alkaline (3 V), and ±8-V split supplies. |
| Gain-Bandwidth Product | 3 MHz - enables stable closed-loop operation up to ~200 kHz with moderate gain (e.g., AV = 15). |
| Slew Rate | 2.4 V/µs - supports 1-V step response settling within 2 µs at unity gain (0.1% error). |
| Input Bias Current | 1 pA - preserves signal integrity in high-Z sensor interfaces (e.g., pH electrodes, photodiode transimpedance). |
| Shutdown Current | 25 µA/channel - reduces system standby power by >95% vs active mode (550 µA). |
| Rail-to-Rail I/O | Input: 0 V to VDD; Output: within 150 mV of rails at 1 mA - maximizes dynamic range in low-voltage ADC driver stages. |
| Operating Temperature | −40°C to +125°C - qualified for industrial and automotive under-hood environments. |
Pinout & Package
TLV2371IDBVTG4 uses a 5-pin SOT-23 (DBV) package measuring 2.90 mm × 1.60 mm, optimized for high-density PCB layouts and automated assembly.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - OUT | Output | Amplified signal output; capable of sourcing/sinking ≥5 mA into resistive loads. |
| 2 - GND | Ground Reference | Primary return path for supply and signal currents; must be low-impedance connection. |
| 3 - IN+ | Noninverting Input | High-impedance (≥1 TΩ) node accepting signals from 0 V to VDD without clipping. |
| 4 - IN− | Inverting Input | High-impedance feedback node; used in inverting configurations or with external compensation. |
| 5 - VDD | Positive Supply | Single positive rail input; accepts 2.7–16 V; no internal negative rail required. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail input and output | Enables full-scale signal swing in 3-V systems, preserving SNR when driving 12-bit SAR ADCs. |
| 550 µA/channel quiescent current | Permits continuous operation for >1 year on a 200-mAh coin cell in always-on sensor nodes. |
| 1 pA input bias current | Minimizes offset error in 10-MΩ+ source impedances, critical for precision thermistor or strain gauge amplification. |
| Active-low shutdown (SHDN) | Reduces total system current to <30 µA; compatible with GPIO wake-up from microcontrollers like MSP430. |
| 3-MHz bandwidth at low power | Supports anti-aliasing filtering and fast-settling buffer stages in portable data acquisition systems. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2371IDBVR | Same silicon, tape-and-reel packaging (no G4 suffix); identical electrical specs and pinout. | No functional difference; intended for high-volume automated assembly rather than sample evaluation. | Select TLV2371IDBVR for production runs requiring reel delivery; TLV2371IDBVTG4 is ideal for prototyping and small-batch validation. |
| TLV2461CDCKR | Higher quiescent current (550 µA → 550 µA same), but wider GBW (6.4 MHz), lower VOS (150 µV typ), no shutdown. | Lacks shutdown function; better for performance-critical, continuously powered stages where power budget allows. | Choose TLV2461CDCKR when higher speed and lower offset outweigh need for power gating; not drop-in replaceable due to missing SHDN pin. |
Compared with TLV2371IDBVTG4, TLV2371IDBVR offers identical performance in volume packaging, while TLV2461CDCKR trades shutdown capability for enhanced AC performance - making the former a logistics alternative and the latter a functional trade-off for non-shutdown applications.

FAQ
What is the maximum supply voltage for TLV2371IDBVTG4?
The absolute maximum supply voltage for TLV2371IDBVTG4 is 16.5 V, but the recommended operating range is 2.7 V to 16 V. Operation above 16 V risks permanent damage. At 16 V, the device maintains 3-MHz bandwidth and 2.4 V/µs slew rate, supporting legacy ±8-V systems and high-voltage industrial rails.
Does TLV2371IDBVTG4 have a shutdown pin?
TLV2371IDBVTG4 does not include a shutdown pin - it is the non-shutdown variant in the TLV237x family. The TLV2370IDBVTG4 is the pin-compatible version with active-low SHDN functionality. TLV2371IDBVTG4 draws 550 µA continuously and cannot be externally gated to reduce current.
What is the input offset voltage specification for TLV2371IDBVTG4?
TLV2371IDBVTG4 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. This value is measured with VDD = 2.7–15 V, VIC = VDD/2, and RL = 50 Ω, and remains stable across supply voltage variations.
Can TLV2371IDBVTG4 drive capacitive loads?
Yes, TLV2371IDBVTG4 is unity-gain stable and characterized for capacitive loads up to 100 pF, with 65° phase margin at CL = 100 pF and RL = 2 kΩ. For loads >100 pF, external isolation resistance (e.g., 10–50 Ω in series with output) is recommended to maintain stability and prevent peaking.
Is TLV2371IDBVTG4 RoHS compliant and lead-free?
Yes, TLV2371IDBVTG4 is RoHS compliant and lead-free, with a matte tin (Sn) lead finish. The DBV (SOT-23) package meets JEDEC J-STD-020 moisture sensitivity level 1 (MSL-1), allowing unlimited floor life at ≤30°C/85% RH and standard reflow profiles including Pb-free JEDEC Level 3.
