Overview
The TLC2252CDR is a dual operational amplifier from Texas Instruments, part of the TLC225x family. These devices are known for their high input impedance, low noise, and rail-to-rail output performance, making them ideal for small-signal conditioning in high-impedance sources such as piezoelectric transducers. The TLC2252CDR is particularly suited for battery-powered applications due to its very low power consumption of 35 µA per channel. It is fully specified for both single-supply and split-supply operations, enhancing its versatility in various design scenarios.
