OPA320 - CMOS Operational Amplifier

General Description

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.
