NOTES:
11. V_SELx = Input voltage to perform proper function.
12. The algebraic convention, whereby the most negative value is a minimum and the most positive a maximum, is used in this
data sheet.
13. 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.
14. Flatness is defined as the difference between maximum and minimum value of ON-resistance over the specified analog signal
range.
15. 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.
16. Limits established by characterization and are not production tested.
17. Click and Pop Reduction specifications are limited by test equipment.
