Overview
The OPA2320AIDRGT is a dual, precision, zero-crossover, 20-MHz CMOS operational amplifier produced by Texas Instruments. This device is part of the OPA320 series, which is optimized for very low noise and wide bandwidth while operating on a low quiescent current. The OPA2320 is ideal for low-power, single-supply applications and is well-suited for driving sampling analog-to-digital converters (ADCs), signal conditioning, and sensor amplification.
