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-

tion capacitor, C

f. 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.
