Texas Instruments TLC27M2AIDRG4

Overview

TLC27M2AIDRG4 from Texas Instruments is a dual precision LinCMOS operational amplifier with 5 mV max input offset voltage at 25°C, −40°C to 85°C operating temperature range, and rail-to-rail output swing down to the negative rail. It delivers low power consumption (210–560 µA per amplifier at VDD = 5 V), high input impedance (10¹² Ω typ), 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 TLC27M2AIDRG4 datasheet, TLC27M2AIDRG4 pinout, TLC27M2AIDRG4 application, or TLC27M2AIDRG4 equivalent, key selection considerations include its I-suffix industrial temperature rating, D-package SOIC-8 footprint, single-supply operation capability, and verified performance in transducer interfacing and active filtering where input bias current < 60 pA and CMRR ≥ 60 dB are required.

Technical Context

The TLC27M2AIDRG4 uses silicon-gate LinCMOS process technology to achieve stable offset voltage drift (1.7 µV/°C over 25°C–85°C) and latch-up immunity. 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.

Each amplifier features internal ESD protection rated to 2000 V (MIL-STD-883C, Method 3015.2), surge-current tolerance of ±100 mA on inputs/outputs, and operates across 4 V to 16 V supply range. The device exhibits unity-gain bandwidth of 525 kHz (typ, VDD = 5 V) and phase margin of 40°, ensuring stable closed-loop performance in unity-gain buffer configurations.

FAQ

What is the maximum input offset voltage specification for TLC27M2AIDRG4 at 25°C?

The TLC27M2AIDRG4 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 test conditions. This value applies across the full industrial temperature range (−40°C to +85°C) with a worst-case drift of 1.7 µV/°C.

Does TLC27M2AIDRG4 support true single-supply operation with inputs referenced to ground?

Yes, the TLC27M2AIDRG4 supports true single-supply operation: its common-mode input voltage range extends to −0.2 V (with VDD = 5 V), allowing ground-referenced inputs without external level-shifting. This is confirmed in the "Recommended Operating Conditions" table and explicitly stated in the device description.

What package type and pin count does TLC27M2AIDRG4 use?

The TLC27M2AIDRG4 uses an 8-pin SOIC (Small Outline Integrated Circuit) package designated as "D package" per TI's packaging nomenclature. The "R" in the part number indicates tape-and-reel packaging, and the "G4" suffix denotes RoHS-compliant lead finish.

Can TLC27M2AIDRG4 drive capacitive loads directly, and what is its phase margin?

The TLC27M2AIDRG4 has a phase margin of 40° at unity gain with CL = 20 pF (VDD = 5 V, TA = 25°C), as measured per Figure 3 in the datasheet. It is stable driving moderate capacitive loads (< 100 pF) but requires isolation resistor for larger loads; direct driving of >1000 pF loads is not recommended without compensation.

Is TLC27M2AIDRG4 pin-compatible with other devices in the TLC27Mx family?

Yes, all TLC27Mx dual op-amps-including TLC27M2AIDRG4, TLC27M2CDR, and TLC27M7IDR-share identical SOIC-8 pinouts and pin functions. This allows drop-in replacement across offset voltage grades (2 mV, 5 mV, 10 mV, 500 µV) and temperature grades (C, I, M) without PCB changes.
