Overview
The OPA2320AIDRGR is a dual, precision, zero-crossover, 20-MHz operational amplifier 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 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.
