Overview
The TLC277CPS 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 family, known for their low offset voltage drift, high input impedance, low noise, and speeds comparable to general-purpose BiFET devices. The TLC277CPS is particularly noted for its high precision, with a trimmed offset voltage of 500 μV max at 25°C and an input offset voltage drift of typically 0.1 μV/month, including the first 30 days.
