Texas Instruments TLC27M7IDG4

Overview

TLC27M7IDG4 from Texas Instruments is a dual precision operational amplifier using LinCMOS technology, featuring 500 µV max input offset voltage at 25°C, 0.1 µV/month offset drift, and rail-to-rail output swing down to the negative rail. It operates from 4 V to 16 V over −40°C to 85°C and delivers low noise (32 nV/√Hz at 1 kHz) and low power (2.1 mW typical at 5 V), making it suitable for high-accuracy sensor signal conditioning in industrial instrumentation.

For engineers reviewing the TLC27M7IDG4 datasheet, TLC27M7IDG4 pinout, TLC27M7IDG4 application, or TLC27M7IDG4 equivalent, key selection criteria include its guaranteed 500 µV input offset voltage grade, extended common-mode range below ground, single-supply compatibility, and temperature-stable performance across −40°C to 85°C industrial environments.

Technical Context

The TLC27M7IDG4 implements a dual-channel LinCMOS op-amp architecture with silicon-gate process enabling superior offset voltage stability versus metal-gate alternatives. Its input stage supports common-mode voltage down to −0.2 V (at VDD = 5 V), and output swings to within 50 mV of GND and 3.9 V (at VDD = 5 V, 25°C).

It achieves 525 kHz unity-gain bandwidth and 0.40 V/µs slew rate at VDD = 5 V, with phase margin of 40°, supporting stable closed-loop operation in precision DC-coupled and low-frequency AC applications without external compensation.

FAQ

What is the maximum input offset voltage specification for TLC27M7IDG4 over temperature?

The TLC27M7IDG4 has a maximum input offset voltage of 500 µV at 25°C and 2000 µV across the full −40°C to +85°C operating range, as specified in the electrical characteristics table for the I-suffix grade at VDD = 5 V. This guaranteed limit enables predictable error budgeting in precision analog designs without recalibration.

Does TLC27M7IDG4 support true single-supply operation with inputs referenced to ground?

Yes, the TLC27M7IDG4 supports true single-supply operation: its common-mode input voltage range extends to −0.2 V at VDD = 5 V (and to 0 V at VDD = 10 V), allowing both inputs to be tied directly to ground or slightly below in properly biased configurations. This eliminates the need for level-shifting circuitry in 0–5 V systems.

What is the recommended minimum supply voltage for TLC27M7IDG4 at −40°C?

The TLC27M7IDG4 requires a minimum supply voltage of 4 V across its full operating temperature range of −40°C to +85°C. At −40°C, operation below 4 V is not characterized or guaranteed - attempting to operate at 3 V (which is only valid for C-suffix parts at 0°C–70°C) may result in degraded output swing, increased offset, or instability.

Can TLC27M7IDG4 drive capacitive loads without oscillation?

The TLC27M7IDG4 is unity-gain stable with a phase margin of 40° at 25°C (VDD = 5 V, CL = 20 pF). It can safely drive ≥20 pF loads without external compensation; for loads >100 pF, a small series resistor (10–50 Ω) at the output is recommended to maintain stability, as confirmed by the device's B1 bandwidth and φm test conditions.

Is TLC27M7IDG4 pin-compatible with other devices in the TLC27Mx family?

Yes, all TLC27Mx dual op-amps-including TLC27M2, TLC27M2A, TLC27M2B, and TLC27M7-in D (SOIC-8), P (PDIP-8), and PW (TSSOP-8) packages share identical pinouts. The TLC27M7IDG4 is functionally and physically interchangeable with TLC27M2IDG4 or TLC27M2AIDG4 on the same footprint, differing only in offset voltage grade and associated parameters.
