DESCRIPTION
The OPA378 and OPA2378 represent a new generation of Zerø-Drift, micro POWER™ operational amplifiers that use a proprietary auto-calibration technique to provide minimal input offset voltage (20μV) and offset voltage drift (0.1μV/°C). The bination of low input voltage noise, high gain bandwidth (900k Hz), and low power (150μA max) enable these devices to achieve optimum performance for low-power precision applications. In addition, the...
