5.0 POWER SUPPLIES
Noise spikes on the V
errors as the comparator will respond to this noise. A low in-
ductance tantalum filter capacitor should be used close to the
converter V
mended. If an unregulated voltage is available in the system,
a separate LM340LAZ-5.0, TO-92, 5V voltage regulator for
the converter (and the other analog circuitry) will greatly re-
duce digital noise on the V

A single point analog ground that is separate from the logic
ground points should be used. The power supply bypass ca-
pacitor and the self-clocking capacitor (if used) should both
be returned to the digital ground. Any V
analog input filters capacitors, or input signal shielding should
be returned to the analog ground point.
