NOTES:
8. Vlogic = Input voltage to perform proper function.
9. The algebraic convention, whereby the most negative value is a minimum and the most positive a maximum, is used in this data sheet.
10. Parameters with MIN and/or MAX limits are 100% tested at +25°C, unless otherwise specified. Temperature limits established by
characterization and are not production tested.
11. Flatness is defined as the difference between maximum and minimum value of ON-resistance over the specified analog signal range.
12. Limits established by characterization and are not production tested.
13. 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-.
