operation. Digital circuitry grounds must be connected to
the digital supply common.
In applications where the ADC data outputs and control
signals are connected to a continuously active micropro
-
cessor bus, it is possible to get errors in the conversion
results.
These errors are due to feed-through from the
microprocessor to the successive approximation com-
parator. The problem can be eliminated by forcing the
microprocessor
into a “Wait” state during conversion or
by using three-state buffers to isolate the ADC data bus.
