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 (± 5V@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.
