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 (± 1.0V) 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.
Low Voltage, Single Supply Operation : 2.7V to 5.5V
Very Low Input Offset Voltage : ± 1.0V typ.
Near Zero Dirft over time and temperature : ± 2.0nV/C typ.
Full Swing Outputs to 10k Load
Power Supply Current : 1.05mA typ./ch (VDD: 5.0V, No Load)
Gain Bandwidth : 4MHz typ.
Operationg Temperature Range : -40 to 125C
Package : MSOP8
