Overview
The TLV274IDR from Texas Instruments is a quad, low-power, wide-bandwidth operational amplifier (opamp) designed for a wide range of applications. It operates from a supply voltage range of 2.7 V to 16 V and is fully specified for 5-V and ±5-V supplies. This opamp is notable for its rail-to-rail output, high slew rate, and low power consumption, making it an ideal alternative to the TLC27x family. The TLV274IDR is particularly suited for battery-powered applications and high-impedance sensor interfaces due to its CMOS inputs and low voltage operation.
