Overview
The TLC2272MDG4 is a dual operational amplifier from Texas Instruments, part of the TLC227x family. These devices are known for their rail-to-rail output performance, which increases the dynamic range in both single-supply and split-supply applications. They offer enhanced AC performance with lower noise, input offset voltage, and power dissipation compared to existing CMOS operational amplifiers. The TLC2272MDG4 is particularly suited for small-signal conditioning of high-impedance sources such as piezoelectric transducers and is ideal for applications requiring low power consumption, such as hand-held monitoring and remote-sensing systems.
