Texas Instruments OPA320
The OPA320 (single) and OPA2320 (dual) are a new generation of precision, low-voltage CMOS operational amplifiers optimized for very low noise and wide bandwidth while operating on a low quiescent current of only 1.45 mA. The OPA320 series is ideal for low-power, singlesupply applications. The OPA320 features a linear input stage with zerocrossover distortion that delivers excellent commonmode rejection ratio (CMRR) of typically 114 dB over the full input range.| Part No. | OPA320 |

DESCRIPTION
Low-noise (7 nV/√Hz) and highspeed operation also make them well-suited for driving sampling analog-to-digital converters (ADCs). Other applications include signal conditioning and sensor amplification. The input common mode range extends 100 mV beyond the negative and positive supply rails.
