Product details
Overview
TLV2371IDRG4 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/channel supply current, and operates from 2.7 V to 16 V - enabling use in Li-ion-powered portable blood glucose meters and industrial sensor front-ends.
For engineers reviewing the TLV2371IDRG4 datasheet, TLV2371IDRG4 pinout, TLV2371IDRG4 application, or TLV2371IDRG4 equivalent, key selection criteria include its shutdown capability (25 µA/channel), 1 pA input bias current, −40°C to +125°C industrial temperature range, rail-to-rail output swing at 2.7 V, and compatibility with MSP430 microcontrollers.
Technical Context
The TLV2371IDRG4 uses CMOS input stage architecture to achieve ultra-low input bias current (1 pA) and high input impedance, supporting precision interfacing with high-impedance sensors. Its rail-to-rail input common-mode range extends from GND to VDD, and rail-to-rail output swing delivers full dynamic range even at 2.7-V supply.
It features active-low shutdown control (SHDN pin), reducing supply current to 25 µA/channel while maintaining fast turnon/turnoff times (0.8 µs / 1 µs). The device is internally compensated for unity-gain stability with 65° phase margin into 100-pF capacitive load.
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 ±1.35 V to ±8 V split supplies. |
| Gain-Bandwidth Product | 3 MHz - enables stable closed-loop operation up to ~200 kHz in unity-gain buffer or active filter configurations. |
| Slew Rate | 2.4 V/µs - supports 1-Vpp signals up to ~380 kHz without slew-induced distortion. |
| Input Bias Current | 1 pA - minimizes voltage error in high-impedance transducer interfaces (e.g., pH electrodes, photodiode TIA feedback). |
| Input Offset Voltage | 4.5 mV max (25°C) - ensures ≤1.2 mV error in 12-bit ADC front-end with 3-V reference. |
| Shutdown Current | 25 µA/channel - reduces system standby power by >95% vs active mode (550 µA), critical for battery longevity. |
| Operating Temperature | −40°C to +125°C - qualified for industrial automation, white goods motor control, and automotive under-hood sensing. |
Pinout & Package
TLV2371IDRG4 is packaged in an 8-pin SOIC (D package), 4.90 mm × 3.91 mm body size, with standard JEDEC MS-012AC footprint and gull-wing leads.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (OUT) | Output | Amplified signal output; rail-to-rail swing (0.1 V to VDD − 0.1 V at 1 mA load). |
| 2 (IN−) | Inverting Input | Negative input node; accepts common-mode voltages from GND to VDD. |
| 3 (IN+) | Noninverting Input | Positive input node; same rail-to-rail common-mode range as IN−. |
| 4 (GND) | Ground | Analog ground reference; must be low-impedance connection to minimize noise coupling. |
| 5 (NC) | No Connect | Internally unconnected; electrically floating - leave unconnected on PCB. |
| 6 (OUT) | Output (duplicate) | Redundant output pad per SOIC pinout convention; not functional - do not route. |
| 7 (VDD) | Positive Supply | Main power rail; bypass with 0.1 µF ceramic capacitor placed <2 mm from pin. |
| 8 (NC) | No Connect | Internally unconnected; electrically floating - leave unconnected on PCB. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-Rail Input/Output | Enables full-scale signal conditioning from 0 V to VDD without external level-shifting circuitry. |
| 550 µA/Channel Quiescent Current | Permits continuous operation in multi-day battery-powered handheld test equipment with CR2032 or AA cells. |
| 1 pA Input Bias Current | Reduces offset drift in high-Z sensor interfaces (e.g., thermopiles, piezoresistive bridges) over temperature. |
| 25 µA Shutdown Current | Allows microcontroller-driven power gating in intermittent-sampling systems (e.g., remote environmental sensors). |
| 3-MHz Bandwidth at Low Power | Supports anti-aliasing filtering and signal amplification in 100-kSPS data acquisition systems. |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2371CDR | Same silicon, commercial-grade (0°C to +70°C) temperature range; no I-suffix qualification. | Not rated for industrial environments; unsuitable for white goods or remote sensing deployments above 70°C. | Select TLV2371CDR only for cost-sensitive consumer electronics where ambient temperature stays below 70°C. |
| TLV2461CDR | Higher quiescent current (550 µA → 550 µA same), but 6.4-MHz GBW and 1.6 V/µs slew rate; no shutdown pin. | Lacks shutdown function; wider bandwidth suits higher-frequency active filters but increases power in always-on designs. | Choose TLV2461CDR when bandwidth >3 MHz is required and shutdown is unnecessary - e.g., audio line drivers or high-speed comparators. |
Compared with TLV2371CDR, TLV2371IDRG4 adds guaranteed −40°C to +125°C operation and enhanced ESD robustness; compared with TLV2461CDR, it trades bandwidth for lower power and integrated shutdown - making TLV2371IDRG4 optimal for battery-constrained, wide-temperature industrial signal chains.

FAQ
What is the maximum supply voltage for TLV2371IDRG4?
The absolute maximum supply voltage for TLV2371IDRG4 is 16.5 V, but the recommended operating range is 2.7 V to 16 V. Operation at 16 V enables compatibility with ±8-V split supplies or high-headroom industrial loops. Exceeding 16.5 V risks permanent damage per Absolute Maximum Ratings.
Does TLV2371IDRG4 have a shutdown pin?
No - TLV2371IDRG4 does not include a shutdown pin. Among TLV237x variants, only TLV2370 (6-pin SOT-23), TLV2373, and TLV2375 feature SHDN functionality. TLV2371IDRG4 is the non-shutdown single-channel version in SOIC packaging, confirmed by Pin Functions table and Device Comparison Tables in the datasheet.
What is the input offset voltage specification for TLV2371IDRG4?
TLV2371IDRG4 has a maximum input offset voltage of 4.5 mV at 25°C and 6 mV across the full −40°C to +125°C industrial temperature range. This value is measured with VDD = 2.7–15 V, VIC = VDD/2, VO = VDD/2, and RS = 50 Ω, as specified in Section 7.9 of the datasheet.
Which package type is used for TLV2371IDRG4?
TLV2371IDRG4 uses the 8-pin SOIC (D) package, with body dimensions of 4.90 mm × 3.91 mm. The "DRG4" suffix denotes tape-and-reel packaging per TI's ordering nomenclature, and the "I" prefix confirms industrial temperature grade (−40°C to +125°C).
Can TLV2371IDRG4 drive capacitive loads?
Yes - TLV2371IDRG4 is unity-gain stable and maintains 65° phase margin with up to 100 pF capacitive load, as verified in Figure 20 (Phase Margin vs Capacitive Load). For loads >100 pF, external isolation resistor (e.g., 10–50 Ω in series with output) is recommended to preserve stability.
