OPTIONAL EXTERNAL
COMPONENT INTERACTION
The optional external components have specific desired
functions. Their values are chosen to reduce the bandwidth
and eliminate unwanted high frequency oscillation. They
may, however, cause certain undesirable effects when they
interact. Interaction may occur when the components pro-
duce reactions that are nearly equal to one another. One
example is the coupling capacitor, C
C
, and the compensa-
Typical Performance Characteristics
tion capacitor, C
. These two components are low imped-
ances at certain frequencies. They may couple signals from
the input to the output. Please take careful note of basic
amplifier component functionality when selecting the value of
these components and their placement on a printed circuit
board (PCB).
The optional external components shown in
Figure 4
and
Figure 5
, and described above, are applicable in both single
and split supply voltage configurations.
