Overview
The TLC272ACDR is a precision dual operational amplifier produced by Texas Instruments. It utilizes Texas Instruments' silicon-gate LinCMOS technology, which offers superior offset voltage stability compared to conventional metal-gate processes. This device is part of the TLC272 and TLC277 series, known for their low offset voltage drift, high input impedance, low noise, and speeds similar to those of general-purpose BiFET devices. The TLC272ACDR is particularly suited for applications requiring high precision and reliability, such as transducer interfacing, analog calculations, amplifier blocks, active filters, and signal buffering.
