Overview
The OPA2320AIDR is a dual, precision, zero-crossover, 20-MHz CMOS operational amplifier produced by Texas Instruments. This component is part of the OPAx320 series, which is optimized for very low noise and wide bandwidth while operating on a low quiescent current of only 1.45 mA per channel. 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.
