AK2973
Zero Drift operational amplifiers
1. Device Outline
AK2973 is the dual channel CMOS operational amplifires which is available to output with very low input offset voltage (± 10V) and near zero input offset dirft. It’s operated with very small current consumptions, 17μA/ch. Typ.(VDD:5.0V), which is available to operate full swing signals in input and output. AK2973 is appropriate to portable Sensor Pre Amp. applications.
2. Feature
Wide Supply Operation Range: 1.6V ~ 5.5V (±0.8V ~ ±2.75V) Very Low Input Offset Voltage : ±1V typ. Near Zero Dirft over time and temperature : ±10nV/C typ. Input Rabge : VSS to VDD Full Swing Outputs to 50k Load @[VDD/2] Power Supply Current : 34μA typ.(VDD: 5.0V, No Load) Gain Bandwidth : 80kHz typ.
