OPERATING PRINCIPLES
The DC718 is capable of collecting a block of data sam-
ples from an ADC demonstration circuit initiated either
by an internal generated trigger or an externally supplied
trigger of user-selected polarity. The external trigger is
TTL or 3.3V CMOS compatible. Refer to the QuickEval-II
QUICK START PROCEDURE
