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.
