MIC862
Dual Ultra-Low-Power Op Amp in SOT23-8
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.
Datasheets and support documentation are available on
Micrel’s website at: www.micrel.com.
