Note 3:
The algebraic convention, where the most negative value is a minimum and the most positive value a maximum, is used
in this data sheet.
UCSP parts are 100% tested at +25
°
C only, and guaranteed by design over temperature. μMAX parts are 100% tested at
+85
°
C and +25
°
C and guaranteed by design over temperature.

UCSP on-resistance matching between channels and on-resistance flatness guaranteed by design.
Flatness is defined as the difference between the maximum and minimum value of on-resistance as measured over the
specified analog signal range.
Guaranteed by design.
