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 performance all bypassing capacitors should be

located as close to the op amp as possible and all

capacitors

should

low

ESL

(equivalent

series

inductance), ESR (equivalent series resistance). Surface-

mount ceramic capacitors are ideal.

Supply and Loading Resistive Considerations

The MIC862 is intended for single-supply applications

configured with a grounded load. It is not advisable to

operate the MIC862 under either of the following

conditions:



A grounded load and split supplies (±V)



A single supply where the load is terminated above

ground.

Under the above conditions, if the load is less than 20k

Ω

and the output swing is greater than 1V (peak), there may

be some instability when the output is sinking current.

Capacitive Load

When driv

ing a large capacitive load, a resistor of 500Ω is

recommended to be connected between the op amp

output and the capacitive load to avoid oscillation.
