... MIC863 General Description The MIC863 is a dual low power operational amplifier in SOT23-8 package designed to operate in the range, rail-to-rail output, with input common-mode to ground. The MIC863 provides 450kHz gain-bandwidth product while consuming only a 4.2µA supply current. With low supply voltage and SOT23-8 packaging, MIC863 provides two channels as general-purpose amplifiers for portable and battery-powered applications ...
