Applications
The TLC2272IPW is excellent for small-signal conditioning for high-impedance sources such as piezoelectric transducers. Due to its micropower dissipation levels, it is well-suited for hand-held monitoring and remote-sensing applications. The rail-to-rail output feature makes it a great choice when interfacing with analog-to-digital converters (ADCs). It is also suitable for precision applications and can be used as an upgrade to the TLC27x in standard designs.
