Overview
[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.
