7-6. How to Specify the Hold Detection Period

7-6-1. All Period

By this method, the hold detection period is externally specified by the T/H signal.
Detection starts with the T/H signal ON to perform each hold operation.
Detection ends with the T/H signal OFF to reset the hold.

Note: During the undetermined period, the judging output varies with
fluctuations in the input waveform. However, the H/E output
remains on during the undetermined period. Read the judging
result when the indicated value becomes stable (immediately
before the T/H signal rises).
