| MIC860 Micrel, Inc. MIC860 TeenyTM Ultra Low Power Op Amp 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 30A 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.

Applications Information Power Supply Bypassing Regular supply bypassing techniques are recommended. A 10F capacitor in parallel with a 0.1F 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. Supply and Loading Considerations The MIC860 is intended for single supply applications configured with a grounded load. It is not advisable to operate the MIC860 with either: 1). A grounded load and split supplies (+/-V) or 2). A single supply where the load is terminated above ground. Under the above conditions, if the load is less than 20kOhm and the output swing is greater than 1V(peak), there may be some instability when the output is sinking current.
