Overview
The TLC27M4ACDG4 is a precision quad operational amplifier produced by Texas Instruments. It utilizes Texas Instruments' silicon-gate LinCMOS™ technology, which offers offset voltage stability far exceeding that of conventional metal-gate processes. This device combines a wide range of input offset voltage grades with low offset voltage drift, high input impedance, low noise, and speeds comparable to general-purpose bipolar devices. The TLC27M4 is particularly noted for its low power consumption, making it ideal for applications that were previously reserved for bipolar products but require significantly less power.
