TeenyTM Ultra Low Power Op Amp Final Information
General Description
The MIC861 is a rail-to-rail output, input common-mode to ground, operational amplifier in TeenyTM 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.

Exceeding the absolute maximum rating may damage the device. The device is not guaranteed to function outside its operating rating. Devices are ESD sensitive. Handling precautions recommended. Human body model, 1.5k in series with 100pF. Pin 4 is ESD sensetive Exceeding the maximum differential input voltage will damage the input stage and degrade performance (in particular, input bias current is likely to increase. The offset voltage distribution is centered around 0V. The typical offset number shown, is equal to the standard deviation of the voltage offset distribution.
