Product details
Overview
TLV2371IP 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, 550 µA supply current per channel, and operates from 2.7 V to 16 V - enabling use in Li-ion-powered portable blood glucose meters and industrial remote sensing front-ends.
For engineers reviewing the TLV2371IP datasheet, TLV2371IP pinout, TLV2371IP application, or TLV2371IP equivalent, key selection criteria include its shutdown capability (absent in TLV2371), rail-to-rail I/O performance at 2.7 V, ultra-low 1 pA input bias current, and −40°C to +125°C industrial temperature rating.
Technical Context
The TLV2371IP 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 unity-gain-stable design supports capacitive loads up to 100 pF with ≥65° phase margin, and it features internal compensation for consistent 3-MHz bandwidth across 2.7–16 V supply.
Unlike the TLV2370, the TLV2371IP lacks a shutdown pin - confirmed by pin function tables showing no SHDN terminal in SOIC-8 or PDIP-8 configurations. Its output stage delivers rail-to-rail swing with <0.22 V low-level output voltage at 1 mA load over full temperature range.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Bandwidth | 3 MHz typical at 5 V - enables stable closed-loop gain up to ~100 kHz in unity-gain buffer or active filter designs |
| Slew Rate | 2.4 V/µs typical at 5 V - supports 1-V step response settling within 2 µs at 0.1% accuracy |
| Supply Current | 550 µA/channel at 5 V - allows continuous operation for >1 year on a 200-mAh coin cell in sensor signal conditioning |
| Input Bias Current | 1 pA typical - preserves high-impedance source integrity (e.g., pH electrodes, photodiode transimpedance) |
| Input Offset Voltage | 4.5 mV max at 25°C - ensures ≤10 mV error in 12-bit ADC interfaces with 3.3 V reference |
| Operating Temp | −40°C to +125°C - qualified for industrial automation control modules and automotive under-hood sensor nodes |
| Output Swing | Rail-to-rail - delivers full 0–5 V dynamic range into 10-kΩ load, maximizing ADC utilization |
Pinout & Package
TLV2371IP is available in 8-pin PDIP (0.300″ wide) and 8-pin SOIC packages, both measuring 9.81 mm × 6.35 mm (PDIP) or 4.90 mm × 3.91 mm (SOIC). Pin 1 is marked by a beveled edge or molded dot.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Output | Amplified output node; capable of sourcing/sinking ±5 mA while maintaining rail-to-rail swing |
| 2 | Inverting Input | High-impedance (1 TΩ) negative feedback node; accepts signals from 0 V to VDD |
| 3 | Noninverting Input | High-impedance (1 TΩ) positive input; supports common-mode range from ground to supply rail |
| 4 | Ground | Reference return path for all internal circuitry and output stage; must be low-impedance |
| 5 | No Connect | Internally unconnected; may be left floating or tied to ground for mechanical stability |
| 6 | Output | Duplicate output pin (not used in single-channel TLV2371); electrically identical to Pin 1 |
| 7 | Positive Supply | Primary power rail; accepts 2.7–16 V DC; bypass capacitor required at pin for stability |
| 8 | No Connect | Internally unconnected; may be left floating or tied to ground for mechanical stability |
Key Features
| Feature | Design Value |

Equivalent & Alternatives
The following parts are listed as comparable options for similar operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2370IP | Includes active-low shutdown pin (Pin 8); otherwise identical electrical specs and pinout except NC/Pin 5 repurposed as SHDN | Required where periodic power cycling is needed to extend battery life beyond 5 years in always-on sensor nodes | Select TLV2370IP only if shutdown functionality is mandatory; TLV2371IP offers lower BOM cost when unused pins are undesirable |
| TLC2271CP | Higher 1100 µA supply current, 2.2 MHz GBW, no rail-to-rail input (CMVR = ±1.5 V), 300 µV max VOS | Better offset performance but incompatible with 2.7 V supplies or ground-sensing configurations | Choose TLC2271CP only for precision DC-coupled applications above 4 V supply where offset dominates noise budget |
Compared with TLV2370IP and TLC2271CP, the TLV2371IP provides optimal balance of rail-to-rail operation at 2.7 V, ultra-low input bias, and industrial temperature range - making it the preferred choice for battery-constrained, high-impedance sensor interfaces where shutdown is unnecessary.

FAQ
What is the maximum supply voltage for TLV2371IP?
The TLV2371IP supports a maximum supply voltage of 16 V, with absolute maximum rating at 16.5 V. Operation at 16 V is fully specified across the −40°C to +125°C temperature range, enabling use with ±8-V split supplies or high-voltage battery stacks. Exceeding 16.5 V risks permanent damage per Absolute Maximum Ratings.
Does TLV2371IP have a shutdown feature?
No, TLV2371IP does not include a shutdown feature. Unlike TLV2370IP (which has SHDN on Pin 8), TLV2371IP's Pin 8 is a no-connect terminal. Shutdown functionality is present only in TLV2370, TLV2373, and TLV2375 variants - confirmed by device comparison tables and pin function listings in the TLV237x datasheet.
What package options are available for TLV2371IP?
TLV2371IP is offered exclusively in through-hole packages: 8-pin PDIP (body size 9.81 mm × 6.35 mm) and 8-pin SOIC (body size 4.90 mm × 3.91 mm). The SOT-23 variant (TLV2371DBVR) is a separate orderable part; TLV2371IP denotes the DIP/SOIC industrial-grade version with extended temperature qualification.
Can TLV2371IP drive capacitive loads?
Yes, TLV2371IP is unity-gain stable with capacitive loads up to 100 pF, as verified by phase margin ≥65° in Figure 20 of the datasheet. For loads >100 pF, external series resistance (e.g., 10–50 Ω) at the output is recommended to maintain stability - critical in ADC driver and active filter applications where PCB trace capacitance exceeds 50 pF.
What is the input common-mode voltage range of TLV2371IP?
The TLV2371IP features rail-to-rail input stage with common-mode voltage range from 0 V to VDD across the full −40°C to +125°C temperature range. This allows direct interfacing with ground-referenced sensors and single-supply ADCs without level-shifting circuitry - a key differentiator from older op-amps like TLC2271 that limit CMVR to ±1.5 V.
