Overview
The OPA320AIDBVT is a high-performance, precision operational amplifier (op-amp) manufactured by Texas Instruments. This device is part of the OPA320 series, which includes single and dual versions, optimized for very low noise and wide bandwidth while operating on a low quiescent current of only 1.45 mA. The OPA320AIDBVT is designed for demanding applications requiring fast overdrive recovery, precise linear response, and minimal distortion. It operates from a single-supply voltage range of 1.8 V to 5.5 V, making it suitable for precision, low-power applications that can run directly from batteries without regulation.
