Product details
Overview
TLC271ID from Texas Instruments is a programmable low-power LinCMOS™ operational amplifier with bias-select functionality, 10 mV max input offset voltage at 25°C, –55°C to 125°C operating temperature range, and D-package SOIC-8封装. It enables precision signal conditioning in harsh-environment industrial sensors and battery-powered remote monitoring systems.
For engineers reviewing the TLC271ID datasheet, TLC271ID pinout, TLC271ID application, or TLC271ID equivalent, key selection criteria include its three-bias-mode programmability (high/medium/low), rail-to-rail output swing, ultra-low input bias current (0.6 pA typ), and military-grade temperature qualification.
Technical Context
The TLC271ID implements a silicon-gate LinCMOS™ process architecture that delivers 10¹² Ω typical input impedance and latch-up immunity without bipolar power penalties. Its bias-select pin (Pin 5) configures internal current sources to trade off slew rate (3.6 V/µs high mode), noise (25 nV/√Hz), and supply current (475–1000 µA) across three discrete operating points.
It supports single-supply operation from 5 V to 16 V over –55°C to 125°C, with common-mode input range extending below the negative rail (GND) and output swing including GND. Input protection includes ESD circuits rated to 2000 V per MIL-STD-883C Method 3015.2.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Offset Voltage | 10 mV max at 25°C - sets baseline DC accuracy for sensor front-end amplification |
| Supply Voltage Range | 5 V to 16 V - enables direct interface with 5 V, 12 V, and 15 V industrial rails |
| Operating Temperature | –55°C to 125°C - qualified for under-hood automotive, aerospace, and military systems |
| Input Bias Current | 0.6 pA typical - preserves signal integrity in high-impedance pH, piezoelectric, or photodiode interfaces |
| Slew Rate (High Mode) | 3.6 V/µs at VDD = 5 V - supports >100 kHz closed-loop bandwidth in unity-gain buffer configurations |
| Common-Mode Input Range | Extends to GND - allows true single-supply operation with inputs referenced to system ground |
| Output Voltage Swing | Includes GND - drives logic-level inputs or ADC reference points without level-shifting circuitry |
Pinout & Package
Package: SOIC-8 (D package), 3.9 mm × 4.9 mm body, 1.27 mm pitch, tape-and-reel compatible.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (OFFSET N1) | Offset null input 1 | Connects to external potentiometer wiper for manual input offset trimming |
| 2 (IN–) | Inverting input | Differential input node; accepts signals down to GND in single-supply mode |
| 3 (IN+) | Non-inverting input | Differential input node; common-mode range extends to GND |
| 4 (GND) | Negative supply / reference | System ground return; serves as output swing lower limit and bias reference |
| 5 (BIAS SELECT) | Bias configuration control | Voltage level (GND, VDD/2, or VDD) selects high/medium/low power-performance mode |
| 6 (VDD) | Positive supply | Accepts 5–16 V; powers all internal stages and output driver |
| 7 (OUT) | Amplified output | Delivers rail-to-rail swing (GND to VDD–1.2 V) into 10 kΩ load |
| 8 (OFFSET N2) | Offset null input 2 | Second terminal of external trim network; used with Pin 1 for offset cancellation |
Key Features
| Feature | Design Value |
|---|---|

| Rail-to-rail output swing | Output reaches GND and within 1.2 V of VDD - eliminates need for dual supplies in analog front-ends |
| Ultra-high input impedance | 10¹² Ω typical - prevents loading of high-Z transducers like thermocouples or capacitive sensors |
| ESD protection | 2000 V HBM rating per MIL-STD-883C - ensures robustness during board assembly and field handling |
| Latch-up immunity | Designed-in immunity per JEDEC JESD78 - prevents catastrophic failure during overvoltage transients |

Equivalent & Alternatives
The following parts are listed as comparable options for similar operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLC271IP | Same electrical specs but PDIP-8 package; no tape-and-reel option; 1000 mW power rating vs 725 mW for D package | Preferred for through-hole prototyping or legacy PCBs; lacks SOIC thermal performance in dense layouts | Select when hand-soldering or socket-based validation is required |
| TLC272ID | Dual-channel version in same SOIC-8; shared VDD/GND pins; 10 mV VIO per channel; identical bias-select architecture | Reduces component count in multi-channel sensor arrays; requires careful layout to avoid crosstalk | Choose for space-constrained designs needing two matched amplifiers |

FAQ
What is the maximum supply voltage for the TLC271ID?
The absolute maximum supply voltage for the TLC271ID is 18 V, but the recommended operating range is 5 V to 16 V across its full –55°C to 125°C temperature range. Operation above 16 V risks exceeding internal junction temperature limits and may degrade long-term reliability, even if functional at room temperature. Always observe derating curves in the Dissipation Rating Table for SOIC-8 packaging.
How does the BIAS SELECT pin configure operating modes on the TLC271ID?
The BIAS SELECT pin (Pin 5) on the TLC271ID sets operating mode by voltage level: GND selects low-bias mode (50 µW, 0.03 V/µs), VDD/2 selects medium-bias mode (525 µW, 0.4 V/µs), and VDD selects high-bias mode (3375 µW, 3.6 V/µs). This direct analog control enables real-time power/performance adaptation without digital interface overhead, preserving the TLC271ID's simplicity in resource-constrained systems.
Does the TLC271ID support true single-supply operation with inputs at ground potential?
Yes, the TLC271ID supports true single-supply operation with inputs referenced to GND. Its common-mode input voltage range extends to the negative rail (GND) across all bias modes and temperatures, and the output swings to GND. This allows direct interfacing with ground-referenced sensors and eliminates the need for level-shifting circuitry in battery-powered or isolated systems using the TLC271ID.
What is the input offset voltage drift specification for the TLC271ID over time?
The TLC271ID exhibits typically 0.1 µV/month input offset voltage drift, including the first 30 days of operation. This long-term stability metric-distinct from temperature coefficient (2.1–2.2 µV/°C)-reflects silicon-gate LinCMOS™ process advantages over metal-gate alternatives and ensures minimal calibration drift in deployed systems where the TLC271ID operates continuously for months or years.
Can the TLC271ID drive capacitive loads without instability?
The TLC271ID is unity-gain stable with capacitive loads up to 20 pF, as verified in Figure 32 of the datasheet showing phase margin ≥34° across bias modes. For loads >20 pF, external series resistance (typically 10–100 Ω) at the output is required to maintain stability. This limitation applies equally to all TLC271 variants and must be accounted for in filter or cable-driving applications using the TLC271ID.
