OPA320AIDBVR CMOS Op-Amp Introduction

The OPA320AIDBVR is ideal for single-supply, low-power applications. They are also well-suited for driving sampling analog-to-digital converters due to their low noise (7 nV/Hz) and high-speed operation (ADCs). Signal conditioning and sensor amplification are two other applications.

The OPA320 has a linear input stage with zero crossover distortion that provides an excellent common-mode rejection ratio (CMRR) of typically 114 dB across the entire input range. The input common-mode range exceeds the negative and positive supply rails by 100 mV. Typically, the output voltage swings within 10 mV of the rails.
