Note 2: The algebraic convention is used. The most negative value is shown in the minimum column.
Note 3: UCSP parts are 100% tested at T
A
= +25°C. Limits across the full temperature range are guaranteed by correlation and
design. TQFN parts are guaranteed by correlation and design at - 40°C.
Note 4: R

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, not production tested.
