1 MIC86 Teeny Ultra Low Power Op Amp General Description The MIC86 is a rail-to-rail output, input common-mode to ground, operational amplifier in Teeny SC7 packaging. The MIC86 provides 4kHz gain-bandwidth product while consuming an incredibly low 4.6µA supply current. The SC7 packaging achieves significant board space savings over devices packaged in SOT-2 or MSOP-8 packaging. The SC7 occupies approximately half the board area of a SOT-2 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,.5k in series with pf. 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 V. The typical offset number shown, is equal to the standard deviation of the voltage offset distribution. February 26 M

11 Applications Information Power Supply Bypassing Regular supply bypassing techniques are recommended. A µf capacitor in parallel with a.µf capacitor on both the positive and negative supplies are ideal. For best performance all bypassing capacitors should be located as close to the op amp as possible and all capacitors should be low ESL (equivalent series inductance), ESR (equivalent series resistance). Surface-mount ceramic capacitors are ideal. February 26 M
