General Description
The MIC861 is a rail-to-rail output, input common-mode to
ground, operational amplifier in Teeny™ SC70 packaging.
The MIC861 provides 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.
