Overview
The OPA725AIDBVR is a high-performance operational amplifier (op amp) produced by Texas Instruments. It utilizes a state-of-the-art 12V analog CMOS process, combining outstanding AC performance with low bias current and excellent common-mode rejection ratio (CMRR), power supply rejection ratio (PSRR), and open-loop gain (AOL). This op amp is designed to achieve a 20MHz gain-bandwidth product (GBW) and a slew rate of 30V/µs, making it well-suited for various high-speed and low-noise applications.
