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.
