Product details
Overview
TLC271IP from Texas Instruments is a programmable low-power LinCMOS™ operational amplifier with bias-select functionality, 10 mV max input offset voltage at 25°C, 1.7 MHz unity-gain bandwidth in high-bias mode, and operation from 5 V to 16 V supply across –55°C to 125°C. It features rail-to-rail output swing down to the negative rail and supports single-supply sensor signal conditioning in harsh-environment industrial monitoring systems.
For engineers reviewing the TLC271IP datasheet, TLC271IP pinout, TLC271IP application, or TLC271IP equivalent, key selection criteria include its triple-bias-mode programmability (high/medium/low), ultra-low input bias current (0.6 pA typ), wide temperature range qualification, and compatibility with legacy DIP-8 layouts for drop-in replacement in military-grade analog front-ends.
Technical Context
The TLC271IP uses silicon-gate LinCMOS™ process technology to achieve stable input offset voltage drift (0.1 µV/month) and high input impedance (10¹² Ω typ), distinguishing it from bipolar or JFET op-amps. Its bias-select pin enables dynamic trade-offs between slew rate (3.6 V/µs high-bias), power dissipation (50 µW low-bias), and noise (25 nV/√Hz high-bias) without changing external components.
Designed for full military temperature range (–55°C to 125°C), the device meets MIL-STD-883C ESD protection (2000 V), latch-up immunity, and absolute maximum ratings including ±VDD differential input voltage and 18 V supply limit. Input common-mode range extends below the negative rail, supporting ground-referenced transducer interfacing in single-supply configurations.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Offset Voltage (max) | 10 mV at 25°C - defines worst-case DC error in precision gain stages |
| Supply Voltage Range | 5 V to 16 V - enables direct use with 5 V, 12 V, or 15 V industrial rails |
| Unity-Gain Bandwidth | 1.7 MHz (high-bias) - supports audio-band filtering and moderate-speed signal conditioning |
| Input Bias Current | 0.6 pA typical - minimizes voltage error across high-impedance sensor sources |
| Slew Rate | 3.6 V/µs (high-bias) - allows 1 kHz full-scale sine output at ~5.7 Vpp without distortion |
| Common-Mode Input Range | Extends below negative rail - permits true single-supply operation with ground-referenced inputs |
| ESD Protection | 2000 V per MIL-STD-883C Method 3015.2 - ensures robustness in handling and board assembly |
Pinout & Package

| 4 (GND) | Negative supply / reference | Return path for supply and signal; serves as common-mode reference point |
| 5 (BIAS SELECT) | Bias mode control | Voltage level (GND = low, VDD/2 = medium, VDD = high) selects power/performance operating point |
| 6 (VDD) | Positive supply | Accepts 5–16 V; internal regulation enables stable operation across wide rail variation |
| 7 (OUT) | Amplifier output | Capable of rail-to-rail swing down to GND; drives 10 kΩ loads with <50 mV saturation |
| 8 (OFFSET N2) | Offset null terminal 2 | Completes external trim network; used with Pin 1 for precision DC calibration |
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 |
|---|---|---|---|
| TLC271CP | Same architecture and pinout, but rated for 0°C to 70°C commercial range; 10 mV VIO max at 25°C | Limited to non-military, non-extended-temperature environments such as consumer test equipment | Select TLC271CP only if operating temperature stays within 0°C–70°C and cost is primary constraint |
| TLC272IP | Dual-channel version in same P-package; shares identical per-channel specs and bias-select behavior | Reduces component count in multi-sensor systems but occupies same PCB footprint per channel | Choose TLC272IP when two matched amplifiers are required in the same thermal environment and layout space allows dual-DIP |
Compared with TLC271CP and TLC272IP, the TLC271IP uniquely delivers full military temperature qualification (–55°C to 125°C) in a single-channel DIP-8 package, making it the only option for legacy-replacement analog circuits in defense platforms where extended thermal reliability is non-negotiable.

FAQ
What is the maximum supply voltage rating for the TLC271IP?
The TLC271IP has an absolute maximum supply voltage rating of 18 V, with recommended operating range specified from 5 V to 16 V across its full –55°C to 125°C temperature range. Exceeding 18 V risks permanent damage, and operation below 5 V is not characterized or guaranteed per the datasheet.
How does the BIAS SELECT pin function on the TLC271IP?
The BIAS SELECT pin on the TLC271IP sets operating mode: grounded for low-bias (50 µW), connected to VDD/2 for medium-bias (525 µW), or tied to VDD for high-bias (3375 µW). This adjusts slew rate, noise, and bandwidth dynamically-e.g., TLC271IP achieves 3.6 V/µs slew rate only in high-bias mode.
Can the TLC271IP be used in single-supply configurations with ground-referenced inputs?
Yes-the TLC271IP supports true single-supply operation because its common-mode input voltage range extends below the negative rail (GND), and its output swings fully to GND. This allows direct interfacing with ground-referenced transducers without level-shifting circuitry, as confirmed in the recommended operating conditions table for VDD = 5 V and 10 V.
What is the input offset voltage specification for the TLC271IP over temperature?
The TLC271IP has a maximum input offset voltage of 10 mV at 25°C and is characterized across –55°C to 125°C. Its average temperature coefficient is 2.1 µV/°C (typ), resulting in ≤12 mV total drift over the full range-verified in the high-bias mode electrical characteristics table for TLC271M devices.
Does the TLC271IP require external compensation for stability?
No-the TLC271IP is unity-gain stable as shipped, with phase margin ≥46° in high-bias mode at VDD = 5 V and CL = 20 pF. The datasheet confirms stability across all bias modes and supply voltages without external compensation, though capacitive load drive capability decreases above 100 pF.
