Revision 3.0

General Description

The MIC861 is a rail-to-rail output, input common-mode to

ground, operational amplifier in Teeny™ SC70 packaging.

The MIC861 provides a 400kHz gain-bandwidth product

while consuming an incredibly low 4.6μA supply current.

The SC70 packaging achieves significant board space

savings over devices packaged in SOT-23 or MSOP-8

packaging. The SC70 occupies approximately half the

board area of a SOT-23 package.

Datasheets and support documentation are available on

Micrel’s website at: www.micrel.com.
