ASAHI KASEI [AK2920] AK2920 Zero Drift operational amplifiers Feature AK2920 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, 800μA typ./ch (VDD:5.0V), which is available to operate full swing signals in output. AK2920 is appropriated to Sensor Pre Amp. applications. … Low Voltage, Single Supply Operation : 2.7V - 5.5V … Very Low Inp.
