NOTES:
7. V
IN
= Input voltage to perform proper function.
8. The algebraic convention, whereby the most negative value is a minimum and the most positive a maximum, is used in this data sheet.
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.
10. Flatness is defined as the difference between maximum and minimum value of on-resistance over the specified analog signal range.
11. 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.
12. Limits established by characterization and are not production tested.
