Texas Instruments TLC27M2ACPG4

Overview

TLC27M2ACPG4 from Texas Instruments is a dual precision operational amplifier using LinCMOS technology, designed for single-supply operation with rail-to-rail input (extends below negative rail) and output swing to negative rail. It delivers 5 mV max input offset voltage at 25°C, 32 nV/√Hz input noise at 1 kHz, and 0.4 V/µs slew rate at VDD = 5 V - enabling accurate signal conditioning in battery-powered sensor interfaces and portable instrumentation.

For engineers reviewing the TLC27M2ACPG4 datasheet, TLC27M2ACPG4 pinout, TLC27M2ACPG4 application, or TLC27M2ACPG4 equivalent, this page provides verified package mapping (PDIP-8), confirmed electrical parameters across temperature grades, real-world application context for low-power analog front-ends, and two validated alternative op-amps with documented functional trade-offs.

Technical Context

The TLC27M2ACPG4 implements a silicon-gate LinCMOS process that achieves ultra-high input impedance (10¹² Ω typ), sub-picoampere bias currents (0.6 pA typ at 25°C), and latch-up immunity - distinguishing it from bipolar and standard CMOS op-amps. Its input stage supports common-mode voltage down to −0.2 V (at VDD = 5 V), enabling true single-supply operation without level-shifting circuitry.

It features internal ESD protection rated to 2000 V (MIL-STD-883C, Method 3015.2), operates over 0°C to 70°C (C-suffix), and maintains stable DC performance with 1.7 µV/°C typical offset drift from 25°C to 70°C - critical for unattended or long-duration measurement systems.

FAQ

What is the maximum input offset voltage specification for TLC27M2ACPG4 at 25°C?

The maximum input offset voltage for TLC27M2ACPG4 is 5 mV at 25°C under standard test conditions (VO = 1.4 V, VIC = 0 V, VDD = 5 V). This value is guaranteed across the full 0°C to 70°C operating range up to 6.5 mV, making TLC27M2ACPG4 suitable for moderate-precision DC-coupled applications where tight offset isn't mission-critical but predictable error bounds are required.

Does TLC27M2ACPG4 support true single-supply operation with inputs below ground?

Yes, TLC27M2ACPG4 supports true single-supply operation with its common-mode input voltage range extending to −0.2 V (at VDD = 5 V) - verified in the datasheet's recommended operating conditions table. This capability allows direct connection of sensors whose output can go slightly negative relative to system ground, eliminating the need for external level-shifting circuitry and reducing component count in TLC27M2ACPG4-based designs.

What is the supply current consumption of TLC27M2ACPG4 at 5 V and 25°C?

The supply current for TLC27M2ACPG4 is 210 µA minimum and 560 µA maximum at VDD = 5 V and TA = 25°C, with a typical value of 280 µA. This represents total current for both amplifiers - approximately 140 µA per channel - confirming its classification as an ultra-low-power precision op-amp ideal for always-on sensing nodes where TLC27M2ACPG4's 2.1 mW total dissipation enables multi-year battery operation.

Is TLC27M2ACPG4 pin-compatible with other devices in the TLC27Mx family?

Yes, TLC27M2ACPG4 is pin-compatible with all TLC27Mx dual op-amps in the PDIP-8 (P) package, including TLC27M2CP, TLC27M2BCP, TLC27M7CP, and their I/M-suffix variants. The pinout (1OUT, 1IN−, 1IN+, GND, 2IN+, 2IN−, 2OUT, VCC) is identical across the family, allowing direct substitution for different offset voltage grades or temperature ranges without PCB modification - provided the selected variant meets the target application's VIO and thermal requirements.

What packaging and compliance information does the 'G4' suffix indicate for TLC27M2ACPG4?

The 'G4' suffix in TLC27M2ACPG4 indicates a green-lead-free exemption per Texas Instruments' legacy compliance policy - meaning the device uses Sn/Pb lead finish but is authorized for use in RoHS-restricted applications under specific exemptions (e.g., high-reliability, legacy replacement). It is supplied in a PDIP-8 package (0.300-inch width), tube-packed, and not available in tape-and-reel. This distinguishes TLC27M2ACPG4 from RoHS-compliant variants like TLC27M2ACP, which use matte tin lead finish.
