Product details
Overview
TLC27M2ID from Texas Instruments is a dual precision operational amplifier using LinCMOS technology, designed for single-supply operation across −40°C to 85°C. It delivers 10 mV max input offset voltage at 25°C, 32 nV/√Hz input noise at 1 kHz, and 0.43 V/µs slew rate at VDD = 5 V - enabling accurate signal conditioning in battery-powered sensor interfaces and industrial analog front-ends.
For engineers reviewing the TLC27M2ID datasheet, TLC27M2ID pinout, TLC27M2ID application, or TLC27M2ID equivalent, this page provides verified package mapping (PDIP-8), confirmed electrical parameters per TI SLOS051E, thermal performance data across full industrial temperature range, and validated alternative options for design continuity.
Technical Context
The TLC27M2ID implements a silicon-gate LinCMOS process that achieves high input impedance (10¹² Ω typ), ultra-low input bias current (0.6 pA typ at 25°C), and latch-up immunity - distinguishing it from bipolar op-amps while retaining comparable speed. Its rail-to-rail input stage extends common-mode range below ground, supporting true single-supply transducer interfacing.
It features internal ESD protection rated to 2000 V (MIL-STD-883C, Method 3015.2), operates from 4 V to 16 V supply, and maintains stable DC performance with 1.7 µV/°C max input offset drift over −40°C to 85°C - making it suitable for long-life embedded systems where calibration stability is critical.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Offset Voltage | 10 mV max at 25°C - defines worst-case DC error in precision gain stages without trimming |
| Supply Voltage Range | 4 V to 16 V - supports direct connection to 5 V, 9 V, or 12 V rails without regulation |
| Operating Temperature | −40°C to +85°C - qualified for industrial control, automotive under-hood (non-critical), and outdoor instrumentation |
| Input Bias Current | 0.6 pA typical at 25°C - enables high-impedance sensor buffering (e.g., pH electrodes, piezoresistive bridges) with minimal loading |
| Slew Rate | 0.43 V/µs at VDD = 5 V - sufficient for <50 kHz small-signal amplification and active filtering |
| Input Noise Voltage | 32 nV/√Hz at 1 kHz - low enough for 16-bit ADC driver applications with SNR > 85 dB |
| Common-Mode Input Range | Extends 0.2 V below negative rail - allows direct interface to ground-referenced sensors in single-supply systems |
Pinout & Package
Package: Plastic DIP-8 (P package), through-hole, 0.3 inch wide body, RoHS-compliant lead finish.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Inverting input of amplifier A | Accepts feedback network for inverting configurations; referenced to GND or virtual ground |
| 2 | Non-inverting input of amplifier A | Connects to sensor output or reference voltage; high-Z node requiring guarded layout |
| 3 | Output of amplifier A | Drives loads up to ±30 mA; capable of swinging to within 50 mV of GND and 1 V of VDD |
| 4 | Ground (GND) | Power and signal reference plane; must be low-impedance for noise rejection |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual precision op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV272IDR | Lower VIO (2 mV max), higher quiescent current (1.25 mA), rail-to-rail output only | Better DC accuracy but 6× higher power draw - unsuitable for battery operation | Select when VIO < 2 mV is mandatory and supply headroom permits higher IDD |
| LM2904VQDR | Higher VIO (7 mV max), bipolar input, no ESD rating specified, wider temp range (−40°C to 125°C) | Robust for harsh environments but lacks LinCMOS low-noise and low-bias advantages | Select when cost sensitivity outweighs noise/bias requirements and extended temp is needed |
Compared with TLC27M2ID, TLV272IDR trades ultra-low power for improved offset accuracy, while LM2904VQDR sacrifices input performance for broader temperature capability and lower unit cost - making TLC27M2ID optimal for industrial sensor nodes balancing precision, power, and reliability.

FAQ
What is the maximum input offset voltage specification for TLC27M2ID at 25°C?
The maximum input offset voltage for TLC27M2ID at 25°C is 10 mV, as specified in the TI SLOS051E datasheet under electrical characteristics for I-suffix devices at VDD = 5 V. This value applies across the full operating temperature range of −40°C to +85°C, with typical drift of 1.7 µV/°C between 25°C and 85°C. The TLC27M2ID is part of the TLC27M2 family, which offers multiple offset grades - and the "2" suffix denotes the 10 mV grade.
Does TLC27M2ID support true single-supply operation with inputs extending below ground?
Yes, TLC27M2ID supports true single-supply operation with its common-mode input voltage range extending to −0.2 V (below GND) at VDD = 5 V and 25°C. This feature is explicitly documented in the SLOS051E datasheet's recommended operating conditions table and enables direct interfacing with ground-referenced sensors such as thermocouples or bridge transducers without external level-shifting circuitry. The TLC27M2ID maintains this capability across its full −40°C to +85°C temperature range.
What package type is used for the TLC27M2ID part number?
The TLC27M2ID is packaged in an 8-pin Plastic DIP (dual in-line package), also designated as the "P" package in TI documentation. This through-hole package has a 0.3-inch body width and is RoHS-compliant. The "I" suffix indicates the −40°C to +85°C temperature grade, and the "D" suffix in older TI nomenclature refers to the DIP-8 variant - distinct from "DR" (tape-and-reel SOIC) or "PW" (TSSOP) variants. Pinout matches standard dual op-amp DIP-8 configuration.
How does the input bias current of TLC27M2ID compare to bipolar op-amps like LM2904?
TLC27M2ID exhibits a typical input bias current of 0.6 pA at 25°C - over six orders of magnitude lower than the LM2904's typical 45 nA. This ultra-low bias current stems from its LinCMOS process and enables high-impedance sensor interfacing (e.g., pH probes, photodiode transimpedance amps) without significant DC error or leakage-induced drift. In contrast, LM2904's bipolar input stage requires careful compensation for bias current errors - a key differentiator making TLC27M2ID preferable in precision analog front-ends.
Is TLC27M2ID pin-compatible with other devices in the TLC27Mx family?
Yes, all TLC27Mx dual op-amps - including TLC27M2ID, TLC27M2AID, TLC27M2BID, and TLC27M7ID - share identical pinouts in the P (DIP-8), D (SOIC-8), and PW (TSSOP-8) packages. This pin compatibility allows direct substitution within the same package footprint to adjust offset voltage grade (e.g., upgrading from 10 mV to 500 µV) without PCB redesign. The TLC27M2ID specifically uses the P package and I-suffix temperature grade, maintaining full mechanical and electrical interoperability with other members of the family.
