4. VLOGIC = Input voltage to perform proper function.
5. The algebraic convention, whereby the most negative value is a minimum and the most positive a maximum, is used in this data sheet.
6. Flatness is defined as the difference between maximum and minimum value of on-resistance over the specified analog signal range.
7. RON matching between channels is calculated by subtracting the channel with the highest max RON value from the channel with lowest max
RON value, between L and R or between D+ and D-.
8. Parts are 100% tested at +25°C. Over temperature limits established by characterization and are not production tested.
