MIC863
Dual Ultra Low Power Op Amp in SOT23-8
Final Information
General Description
The MIC863 is a dual low power operational amplifier in
SOT23-8 package. It is designed to operate in the 2V to 5V
range, rail-to-rail output, with input common-mode to ground.
The MIC863 provides 450kHz gain-bandwidth product while
consuming only a 4.2µA supply current.
With low supply voltage and SOT23-8 packaging, MIC863
provides two channels as general-purpose amplifiers for
portable and battery-powered applications. Its package pro-
vides the maximum performance available while maintaining
an extremely slim form factor. The minimal power consump-
tion of this IC maximizes the battery life potential.

Exceeding the absolute maximum rating may damage the device.
The device is not guaranteed to function outside its operating rating.
Devices are ESD sensitive. Handling precautions recommended. Human body model, 1.5k in series with 100pF. Pin 4 is ESD sensitive
Exceeding the maximum differential input voltage will damage the input stage and degrade performance (in particular, input bias current is
likely to increase.
DC signal referenced to input. Refer to Typical Characteristics graphs for AC performance.
