MP8102 - ULTRA LOW POWER, 1.8V, 600KHZ OP AMP
APPLICATION 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 is ideal. For the 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) and low ESR (Equivalent Series Resistance). Surface mount ceramic capacitors are ideal.
