AK2970
Zero Drift Operational Amplifier
1. General Description
AK2970 is the dual channel CMOS operational amplifires which is available to output with very low input offset
voltage (± 5V@10V) and near zero input offset dirft.
It’s operated with very small current consumptions, 2mA typ. (VDD:10V), which is available to operate full swing
signals in output. AK2970 is appropriate to Sensor Pre Amp. applications.
2. Features
Wide Supply Operation Range: 4.5V ~ 13.2V (±2.25V ~ ±6.6V)
Very Low Input Offset Voltage : ± 5V max. (@VDD:10V)
Near Zero Dirft over time and temperature : ± 20nV/C max. (@VDD:10V)
Input Voltage Range : VSS – VDD
Full Swing Outputs to 10k Load
Power Supply Current : 2mA typ. (@VDD: 10V, No Load)
Gain Bandwidth : 4MHz typ.
Slew Rate : 4V/sec typ.
Operationg Temperature Range : -40 ~ 125C
