MIC860 Functional Characteristics (Continued) September 9, 2014 11 Revision 2.0 Micrel, Inc. MIC860 Application Information Power Supply Bypassing Regular supply bypassing techniques are recommended. A 10µF capacitor in parallel with a 0.1µF capacitor on both the positive and negative supplies are ideal. For best perfor- mance 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 20kΩ and the output swing is greater than 1V(peak), there may be some instability when the output is sinking current.
