Note 2:
Typical values are for
design aid only,
are not guaranteed, and are not subject to production testing. The algebraic con-
vention, where the most negative value is a minimum and the most positive value a maximum, is used in this data sheet.
Note 3:
Guaranteed by design.
Note 4:
On-resistance match between channels and flatness is guaranteed only with bipolar-supply operation. Flatness is defined
as the difference between the maximum and the minimum value of on-resistance as measured at the extremes of the speci-
fied analog range.
Note 5:
Leakage parameters I

by correlation at +25°C.
