the T/H signal is released and the
instant when the indicated value
returns to tracking
1.0ms (max.)
t3: A minimum reset signal width required
for releasing the hold
1.0ms (min.)
Peak hold
The maximum value (peak) in the positive direction of the specified section is held.
Example) All section peak hold
t1: A delay time between the instant when
the T/H signal is inputted and the
instant when the indicated value is held
1.0ms (max.)
t2: A delay time between the instant when
} the T/H signal is released and the
