The OPA320AIDBVT is a precision CMOS Operational Amplifier is a new generation optimized for very low noise and wide bandwidth while operating on a low quiescent current of only 1.45mA. The OPA320 series is ideal for low-power, single-supply applications. Low-noise and high-speed operation also make them well-suited for driving sampling analogue-to-digital converters (ADCs). The OPA320 features a linear input stage with zero-crossover distortion that delivers excellent common-mode rejection ratio (CMRR) of typically 114dB over the full input range. The input common-mode range extends 100mV beyond the negative and positive supply rails. The output voltage typically swings within 10mV of the rails.
