Revision 3.0

General Description

The MIC862 is a dual low-power operational amplifier in an

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

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.
