Texas Instruments TLC27M4AID

Overview

TLC27M4AID from Texas Instruments is a precision quad operational amplifier with trimmed input offset voltage (±5 mV max at 25°C), low offset drift (±0.6 µV/°C), and rail-to-rail output swing including the negative rail. It operates from 4 V to 16 V across −40°C to +85°C, draws only 120 µA quiescent current per two amplifiers at 5 V, and delivers 1.1 MHz unity-gain bandwidth - ideal for low-power sensor signal conditioning in industrial PLC analog I/O modules.

For engineers reviewing the TLC27M4AID datasheet, TLC27M4AID pinout, TLC27M4AID application, or TLC27M4AID equivalent, key selection criteria include its guaranteed ±5 mV input offset voltage grade, SOIC-14 package compatibility, −40°C to +85°C temperature range, and LinCMOS™ process advantages in high-input-impedance (6 TΩ typ) and low-noise (32 nV/√Hz) performance.

Technical Context

The TLC27M4AID implements a LinCMOS™ input stage delivering ultra-low input bias current (±10 pA typ at 25°C) and high common-mode rejection (65–80 dB), enabling accurate DC-coupled amplification in high-impedance source applications such as thermocouple or strain gauge front-ends. Its internal architecture supports single-supply operation with input common-mode range extending to −0.2 V below ground.

It features ESD protection circuitry and inherent latch-up immunity, allowing robust deployment in noisy industrial environments. The device's 0.5 V/µs slew rate and 1.1 MHz unity-gain bandwidth balance precision and moderate-speed signal processing without excessive power consumption.

FAQ

What is the maximum operating temperature range for the TLC27M4AID?

The TLC27M4AID is rated for operation from −40°C to +85°C, as confirmed by its "I" temperature suffix and electrical specifications in Section 6.3 of the datasheet. This range applies across its full supply voltage window (4 V to 16 V) and supports deployment in industrial control cabinets and outdoor instrumentation enclosures without forced cooling.

Does the TLC27M4AID support rail-to-rail input operation?

No, the TLC27M4AID does not support rail-to-rail input. Its common-mode input voltage range extends to −0.2 V below ground and up to VDD − 1.5 V (e.g., 3.5 V at VDD = 5 V), as specified in Table 6.3. However, its output swing does include the negative rail, enabling true single-supply functionality.

Can the TLC27M4AID be used with a 3-V supply?

No, the TLC27M4AID is not rated for 3-V operation. Per Section 6.3, its minimum recommended supply voltage is 4 V over the −40°C to +85°C range. Using 3 V violates recommended operating conditions and may result in degraded parameters including reduced output swing, increased offset, and instability.

What is the typical input bias current of the TLC27M4AID at 25°C?

The typical input bias current of the TLC27M4AID is ±10 pA at 25°C, as stated in Table 6.4 (TLC27M4AC column). This ultra-low value stems from its LinCMOS™ input stage and enables accurate amplification of signals from sources with impedances exceeding 100 MΩ without significant DC error.

Is the TLC27M4AID pin-compatible with other devices in the TLC27Mxx family?

Yes, the TLC27M4AID is pin-compatible with all TLC27Mxx quad op-amps in SOIC-14 (D) package, including TLC27M4ID, TLC27M4CD, and TLC27M4BD. Pin configuration and functions are identical per Table 5-1, allowing direct substitution where electrical specifications meet design requirements.
