[AK2921] AK2921 Zero Drift operational amplifiers Feature AK2921 is the dual channel CMOS operational amplifires which is available to output with very low input offset voltage (+/- 1.0μV) and near zero input offset dirft. It’s operated with very small current consumptions, 260μA typ./ch (VDD:5.0V), which is available to operate full swing signals in output. AK2921 is appropriated to Sensor Pre Amp. applications. … Low Voltage, Single Supply Operation : 1.6V - 5.5V … Very Low Input Offset Vol.
