  • Data Sheet


AK2970 is the dual channel CMOS operational amplifires which is available to output with very low input offset voltage (±5μV@10V) and near zero input offset dirft. It’s operated with very small current consumptions, 1mA typ./ch (VDD:10V), which is available to operate full swing signals in output. AK2970 is appropriated to Sensor Pre Amp. applications.
