Application Information (Continued)
performance of the tantalum will be better. There should also
be large supply reservoir capacitors of about 4700 F on
each supply rail. A larger reservoir capacitor will reduce the
supply ripple and will supply larger current burst require-
ments instead of requiring those large currents to come from
the main power supply transformer.
If adequate bypassing is not provided, the current in the sup-
ply leads, which is a rectified component of the load current,
may be fed back into internal circuitry. This signal may cause
signal distortion to increase.
Layout and Ground Loops
When designing a printed circuit board layout, it is important
to return the load ground, any output compensation ground,
and the low-level (feedback and input) grounds to the circuit
board common ground point through separate paths. Large
currents flowing along a ground conductor will generate volt-
ages which effectively act as signals to the input ground ref-
erence. This can result in high frequency oscillation or ex-
cessive distortion. Output compensation components and
the high frequency supply bypass capacitors should be
placed as close as possible to the IC to reduce the effects of
PCB trace resistance and inductance. For cases where long
traces must exist, widen the traces to minimize their induc-
tance.
