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 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.
