Overview
The OPA320AIDBVR, produced by Texas Instruments, is a precision, low-voltage CMOS operational amplifier. This device is part of the OPA320 series, which includes single and dual versions, such as the OPA320 and OPA2320. The OPA320AIDBVR is optimized for very low noise and wide bandwidth while operating on a low quiescent current of only 1.45 mA. It features a linear input stage with zero-crossover distortion, making it ideal for low-power, single-supply applications.
