Advance Datasheet
Single Low Bias Current, Low Voltage, Rail-to-Rail
Input/Output CMOS Operational Amplifier
AZV831
General Description
Features
The AZV831 is low bias current, low voltage
operational amplifiers which can be designed into a
wide range of applications. The AZV831 has a
quiescent current of 70μA per amplifier at 1.6V.
The AZV831 features optimal performance in low
voltage, low bias current systems. The IC can provide
rail-to-rail output swing under heavy loads. The
common-mode input voltage range could be designed
200mV exceeding the supply voltage range, thus
enables the customer to expand its application scope.
The AZV831 has a maximum input offset voltage of
2.5mV and its operating range is from 1.6V to 5.5V.
