General Description
The MIC863 is a dual low-power operational amplifier in a SOT-23-8 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 450 kHz gain-bandwidth product while consuming only a 4.
2 μA supply current
With low supply voltage and 8-pin SOT-23 packaging, MIC863 provides two channels as general-purpose amplifiers for portable and battery-powered applications.
Its package provides the maximum performance available while maintaining an extremely slim form factor.
The minimal power consumption of this IC maximizes the battery life potential.
