NOTES:
1. N
CONV
n
denotes 8- or 10-bit conversion time (refer to specifications
N4
,
N5
,
P4
and
P5
). In order to achieve the
minimum period between conversions when using level-sensitive triggering, ETRIG must remain asserted this long.
2. Time prior to the end of a conversion that ETRIG must be negated in order to prevent the start of another conversion.
