MIC863 Application Information 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 performance all bypassing capacitors should be located as close to the op amp as possible and all capacitors should be low equivalent series inductance (ESL), equivalent series resistance (ESR). Surface-mount ceramic capacitors are ideal. The MIC863 is intended for single-supply applications configured with a grounded load. It is not advisable to operate the MIC863 under either of the following conditions when the load is less than 20kΩ and the output swing is greater than 1V (peak-to-peak): 1. A grounded load and split supplies (±V) or 2. A single supply where the load is terminated above ground. Under the above listed conditions, there may be some instability when the output is sinking current. May 7, 2014 15 Revision 2.0 Micrel, Inc. MIC863 Package Information(7) 8-Pin SOT-23 (M8) Note: 7.
