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. Interaction may occur for components whose reactances are in close proximity to one another. One
example would be the coupling capacitor, C
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 component functionality when designing in these components.
The optional external components shown in Figure 5 and Figure 6 and described above are applicable in both
single and split voltage supply configurations.
