Optional External Component
Interaction
Although the optional external components have specific
desired functions that are designed to reduce the bandwidth
and eliminate unwanted high frequency oscillations they may
cause certain undesirable effects when they interact. Inter-
action may occur for components whose reactances are in
close proximity to one another. One example would be the
Typical Performance Characteristics
coupling capacitor, C
, and the compensation capacitor, C
f
.
These two components act as low impedances to certain
frequencies which will couple signals from the input to the
output. Please take careful note of basic amplifier compo-
nent functionality when designing in these components.
The optional external components shown in
Figure 4
and
Figure 5
and described above are applicable in both single
and split voltage supply configurations.
