Overview
The TLV272CDR is a low-power, wide-bandwidth operational amplifier (opamp) from Texas Instruments. It is part of the TLV27x family, which operates from 2.7 V to 16 V and is designed for applications requiring rail-to-rail output swings. This opamp is an ideal alternative to the TLC27x family, offering enhanced performance and compatibility with a wide range of supply voltages, including those from rechargeable cells and Li-Ion powered systems. The TLV272CDR is particularly suited for battery-powered applications and high-impedance sensor interfaces due to its CMOS inputs and low voltage operation.
