• Manufacturer: Micrel Semiconductor

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 resis-
tance). Surface-mount ceramic capacitors are ideal.

Supply and Loading Resistive Considerations
The MIC863 is intended for single supply applications config-
ured with a grounded load. It is not advisable to operate the
MIC863 under either of the following conditions when the load
is less than 20kΩ and the output swing is greater than
1V(peak-to-peak):
1). A grounded load and split supplies (±V) or
2). A single supply where the load is terminated above
ground.
Under the above conditions, there may be some instability
when the output is sinking current.
