External signal
By this method, the hold detection section is specified by the SECTION signal.
Detection starts with the SECTION signal ON, and ends with the SECTION signal OFF to perform
each hold operation.
The hold value is maintained until the hold reset signal is turned on.
The hold is released by turning on the T/H signal as a reset signal.
There are tracking sections, detection sections, and hold deciding sections.
(Example) Externally specified section peak hold
t1: A delay time between the instant
when the SECTION signal is
inputted and the instant when the
value to be held is detected
Approximately 1.0ms (MAX.)
t2: A delay time between the instant
when the SECTION signal is
released and the instant when the
value to be held is determined
Approximately 1.0ms (MAX.)
t3: A minimum reset signal width
required for releasing the hold
Approximately 1.0ms (MIN.)
By turning on the SECTION signal again without turning on the T/H signal while the hold is
decided, the hold is released and re-detection is started. For details, see "7-4.Auto reset
function" on page 65.
