Overview
The TLC2272ID is a dual operational amplifier from Texas Instruments, part of the TLC227x family. These devices are known for their high input impedance, low noise, and rail-to-rail output performance, making them suitable for a wide range of applications, including small-signal conditioning for high-impedance sources like piezoelectric transducers. They offer improved AC performance compared to existing CMOS operational amplifiers, with better noise, input offset voltage, and power dissipation. The TLC2272ID is fully specified for both single-supply and split-supply operation, making it versatile for various design needs.
