february 2006 11 m9999- 022706 mic861 micrel, inc. 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 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.
