Note 2: The algebraic convention, where the most negative value is a minimum and the most positive value a maximum, is used in
this data sheet.
Note 3: Parts are tested at +85°C and guaranteed by design over the entire temperature range.

matching specifications for TQFN packaged parts are guaranteed by design.
Note 6: Flatness is defined as the difference between the maximum and minimum value of on-resistance as measured over the
specified analog signal ranges.
Note 7: Guaranteed by design.
