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