Note 2: The algebraic convention, where the most negative value is a minimum and the most positive value is a maximum, is
used in this data sheet.
Note 3: µDFN and SOT23 packaged parts are 100% tested at +25°C. Limits across the full temperature range are guaranteed by
design and correlation. µMAX packaged parts -40°C specifications are guaranteed by design.

Note 5: Flatness is defined as the difference between the maximum and the minimum value of on-resistance as measured over the
specified analog signal ranges.
Note 6: Guaranteed by design.
