Product details
Overview
TLV2371IDR 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 battery-powered blood glucose meters and handheld test equipment.
For engineers reviewing the TLV2371IDR datasheet, TLV2371IDR pinout, TLV2371IDR application, or TLV2371IDR equivalent, key selection criteria include rail-to-rail I/O swing at 2.7-V operation, shutdown capability (25 µA/channel), ultra-low input bias current (1 pA), and industrial-grade temperature range (−40°C to +125°C).
Technical Context
The TLV2371IDR uses CMOS input stage architecture to achieve 1-pA input bias current and rail-to-rail common-mode input range (0 V to VDD). Its fully differential output stage supports rail-to-rail output swing with ±1-mA load capability across the full supply range.
It integrates an active-low shutdown control (SHDN) that reduces supply current to 25 µA/channel while maintaining fast turnon/turnoff times (0.8 µs / 1 µs). The device is specified for stable unity-gain operation with capacitive loads up to 100 pF and exhibits 65° phase margin.
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. |
| Gain-Bandwidth Product | 3 MHz - enables stable closed-loop operation up to ~200 kHz in unity-gain buffer or inverting amplifier configurations. |
| Slew Rate | 2.4 V/µs - supports 1-Vpp signals up to ~380 kHz without slew-induced distortion. |
| Input Bias Current | 1 pA - permits high-impedance sensor interfacing (e.g., pH electrodes, photodiode transimpedance) without significant offset drift. |
| Shutdown Current | 25 µA/channel - reduces system standby power by >95% vs active mode (550 µA), critical for portable medical devices. |
| Input Noise Voltage | 39 nV/√Hz @ 1 kHz - suitable for precision DC-coupled amplification where noise floor must remain below 10 µV RMS in 10-kHz bandwidth. |
| Operating Temperature | −40°C to +125°C - qualified for industrial automation and automotive cabin-sensing environments. |
Pinout & Package
TLV2371IDR is supplied in an 8-pin SOIC (D) package (4.90 mm × 3.91 mm body size), pin-compatible with industry-standard SOIC-8 footprints.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT | Amplifier output - rail-to-rail swing (within 150 mV of rails at 1 mA load); drives 2-kΩ minimum load. |
| 2 | IN− | Inverting input - high-impedance CMOS node; accepts common-mode voltage from GND to VDD. |
| 3 | IN+ | Noninverting input - identical CMOS characteristics as IN−; used for unity-gain follower or noninverting gain stages. |
| 4 | GND | Analog ground reference - must be connected to system AGND plane; no internal connection to digital ground. |
| 5 | NC | No internal connection - electrically isolated; may be left floating or tied to GND for mechanical stability. |
| 6 | OUT | Output - duplicate pin for thermal and current-handling redundancy (not functional; not used in TLV2371). |
| 7 | VDD | Positive supply - accepts 2.7–16 V; requires local 0.1-µF ceramic decoupling capacitor to GND. |
| 8 | NC | No internal connection - electrically isolated; may be left floating or tied to GND for mechanical stability. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail input and output | Enables full dynamic range utilization in single-supply systems (e.g., 3.3-V microcontroller ADC interface) without level-shifting circuitry. |
| 550 µA/channel supply current | Supports >100-hour battery life in coin-cell-powered instrumentation when paired with duty-cycled signal acquisition. |
| 1 pA input bias current | Minimizes voltage error in high-Z sensor interfaces (e.g., 10-MΩ thermistor networks), eliminating need for guard traces or bias compensation resistors. |
| 25 µA/channel shutdown mode | Allows microcontroller-controlled power gating in multi-stage analog front-ends, reducing quiescent power during idle periods. |
| −40°C to +125°C operation | Validated for deployment in unregulated industrial enclosures and automotive under-hood auxiliary sensors. |

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 electrical specs but rated for 0°C to +70°C commercial temperature range; no extended industrial qualification. | Not suitable for deployments outside ambient-temperature office/lab environments. | Select TLV2371CDR only for cost-sensitive consumer electronics where industrial temp grade is unnecessary. |
| TLV2461IDR | Higher 6.4-MHz GBW and 1.6-V/µs slew rate, but higher 550-µA supply current and no shutdown function; input bias current 1300 pA. | Better for higher-speed signal chains (e.g., active filters >500 kHz), but unsuitable where shutdown or ultra-low IB are required. | Choose TLV2461IDR when bandwidth is prioritized over power savings and shutdown capability. |
Compared with TLV2371CDR, TLV2371IDR adds guaranteed operation down to −40°C and up to +125°C - essential for field-deployed instrumentation. Versus TLV2461IDR, TLV2371IDR trades bandwidth for 1000× lower input bias current and integrated shutdown, making it superior for high-impedance, battery-constrained sensing.

FAQ
What is the maximum supply voltage for TLV2371IDR?
The absolute maximum supply voltage for TLV2371IDR 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 full rail-to-rail output swing and 3-MHz bandwidth, supporting legacy 15-V industrial systems and ±8-V split supplies.
Does TLV2371IDR have a shutdown pin?
No, TLV2371IDR does not include a shutdown pin. Unlike TLV2370IDR (which has SHDN on pin 5), the TLV2371IDR variant omits shutdown functionality - confirmed by its pinout table showing pins 5 and 8 as NC (no internal connection). This simplifies layout but removes power-gating capability.
What is the input offset voltage specification for TLV2371IDR?
The TLV2371IDR has a maximum input offset voltage of 4.5 mV at 25°C and 6 mV over the full −40°C to +125°C industrial temperature range. This is measured with VDD = 2.7–15 V, common-mode input at VDD/2, and output at VDD/2 - ensuring predictable DC accuracy in precision sensor amplifiers and reference buffers.
Can TLV2371IDR drive capacitive loads?
Yes, TLV2371IDR is stable driving capacitive loads up to 100 pF, as verified by phase margin measurements (65°) in the datasheet. For loads exceeding 100 pF, external isolation resistance (e.g., 10–50 Ω in series with output) is recommended to maintain stability in unity-gain configurations such as voltage followers.
Is TLV2371IDR pin-compatible with other SOIC-8 op-amps?
TLV2371IDR follows standard SOIC-8 pinout conventions for single op-amps (IN+, IN−, V−/GND, OUT, V+/VDD), matching industry-standard footprints like LM358 and TL071. However, pins 5 and 8 are NC - unlike many competitors that use those pins for shutdown or compensation - so direct replacement requires verification of unused pin handling in existing PCB layouts.
