Texas Instruments TLC27M2AID

Overview

TLC27M2AID from Texas Instruments is a dual precision operational amplifier using LinCMOS technology, featuring 5 mV max input offset voltage at 25°C, −40°C to 85°C operating range, and rail-to-rail output swing down to the negative rail. It delivers low power (210–560 µA supply current per amplifier), high input impedance (10¹² Ω), and low noise (32 nV/√Hz at 1 kHz), making it suitable for battery-powered sensor signal conditioning in industrial monitoring systems.

For engineers reviewing the TLC27M2AID datasheet, TLC27M2AID pinout, TLC27M2AID application, or TLC27M2AID equivalent, key selection criteria include its I-suffix industrial temperature rating, 5 mV offset grade within the TLC27M2 family, D-package SOIC-8 footprint, and compatibility with single-supply 4–16 V operation in transducer interface and active filter designs.

Technical Context

The TLC27M2AID implements silicon-gate LinCMOS process technology to achieve stable offset voltage drift (1.7 µV/°C over 25°C–85°C) and latch-up immunity, distinguishing it from metal-gate CMOS op-amps. Its input stage supports common-mode voltage down to −0.2 V (with VDD = 5 V), enabling true single-supply operation without level-shifting circuitry.

It provides unity-gain bandwidth of 525 kHz (typ, VDD = 5 V), slew rate of 0.40 V/µs (typ), and phase margin of 40° - characteristics optimized for stability in closed-loop configurations with capacitive loads up to 20 pF, as verified in TI's Figure 3 test setup.

FAQ

What is the maximum input offset voltage specification for TLC27M2AID at 25°C?

The TLC27M2AID has a maximum input offset voltage of 5 mV at 25°C, as specified in the "Electrical Characteristics" table for the I-suffix grade under VDD = 5 V conditions. This value applies across the full −40°C to +85°C operating range, with typical drift of 1.7 µV/°C between 25°C and 85°C. The 5 mV grade positions TLC27M2AID between the 10 mV TLC27M2I and the 2 mV TLC27M2BI variants.

Does TLC27M2AID support true single-supply operation with inputs extending below ground?

Yes, the TLC27M2AID supports true single-supply operation with its common-mode input voltage range extending to −0.2 V (with VDD = 5 V) - i.e., 200 mV below GND. This capability is confirmed in the "Recommended Operating Conditions" table and enables direct interfacing with sensors whose output can go slightly negative relative to system ground, without requiring level-shifting circuitry or split supplies.

What package type is used for TLC27M2AID, and is it RoHS-compliant?

The TLC27M2AID is supplied in an SOIC-8 (D) package, 150 mil width, with gull-wing leads. Per Texas Instruments' packaging documentation and product change notices, this D-package variant is lead-free and RoHS-compliant, meeting JEDEC J-STD-020 moisture sensitivity level 1 (MSL-1) requirements for unlimited floor life at ≤30°C/85% RH.

Can TLC27M2AID drive a 100 kΩ load while maintaining rail-to-rail output swing?

Yes, the TLC27M2AID guarantees rail-to-rail output swing into a 100 kΩ load, as verified in the "Electrical Characteristics" tables: VOH ≥ 3 V and VOL ≤ 50 mV (at VDD = 5 V, TA = −40°C to +85°C). This performance holds across the full industrial temperature range and enables direct connection to high-impedance ADC inputs or subsequent op-amp stages without gain loss.

How does the input bias current of TLC27M2AID compare to bipolar op-amps, and why does it matter?

The TLC27M2AID exhibits typical input bias current of 0.6 pA at 25°C - over six orders of magnitude lower than typical bipolar op-amps (e.g., LM358: ~45 nA). This ultra-low bias current prevents significant voltage drop across high-impedance sources (e.g., pH electrodes, photodiode bias networks, or megohm-level potentiometers), preserving signal fidelity and eliminating offset errors that would otherwise require complex compensation circuits.
