MIC862
Dual Ultra Low Power Op Amp in SOT23-8
General Description
The MIC862 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 MIC862 provides 3MHz gain-bandwidth product while
consuming only a 31µA/Channel supply current.
With low supply voltage and SOT23-8 packaging, MIC862
provides two channels as general-purpose amplifiers for por-
table 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.
