[AK2922H]
AK2922H
Zero Drift operational amplifiers
Feature
AK2922H is the dual channel CMOS operational amplifires which is available to output with very low input offset
voltage (± 1.0V) and near zero input offset dirft.
It’s operated with very small current consumptions, 1.05mA typ./ch (VDD:5.0V), which is available to operate full
swing signals in output.
AK2922H is appropriated to Sensor Pre Amp. applications.
