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.
Note 4: WLP parts are 100% tested at +25°C only, and are guaranteed by design over temperature. TSSOP and Thin QFN parts
are 100% tested at +85°C and guaranteed by design over temperature.
Note 5: ∆R

.
Note 6: WLP and Thin QFN on-resistance matching between channels is guaranteed by design.
Note 7: Flatness is defined as the difference between the maximum and minimum value of on-resistance as measured over the
specified analog signal range.
Note 8: Guaranteed by design.
Note 9: Off-isolation = 20 log
