Applications 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 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.
Supply and Loading Resistive Considerations
The MIC862 is intended for single supply applications con-
figured with a grounded load. It is not advisable to operate
the MIC862 under either of the following conditions:
1. A grounded load and split supplies (+/-V)
2. A single supply where the load is terminated
above ground.
Micrel
Under the above conditions, if the load is less than 20kOhm
and the output swing is greater than 1V(peak), there may be
some instability when the output is sinking current.
Capacitive Load
When driving 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.
