NOTES:
4. V_LOGIC = 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. Parts are 100% tested at +25°C. Limits across the full temperature range are guaranteed by design and correlation.
7. Flatness is defined as the difference between maximum and minimum value of on-resistance over the specified analog signal range.
8. Guaranteed by design.
9. r_ON matching between channels is calculated by subtracting the channel with the highest max r_ON value from the channel with lowest max r_ON
value, between L and R or between D+ and D-.
