Overview
The OPA320SAIDBVR is a precision, low-voltage CMOS operational amplifier produced by Texas Instruments. It is part of the OPA320 series, which includes single and dual versions optimized for very low noise and wide bandwidth. The OPA320 is designed for low-power, single-supply applications and features a linear input stage with zero-crossover distortion, making it ideal for precision applications such as driving sampling analog-to-digital converters (ADCs), signal conditioning, and sensor amplification.
