TeenyTM Ultra Low Power Op Amp Final Information
General Description
The MIC860 is a rail-to-rail output, operational amplifier in TeenyTM SC70 packaging. The MIC860 provides 4MHz gain-bandwidth product while consuming an incredibly low 30µA 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.
