Note 4: Flatness is defined as the difference between the maximum and minimum value of on-resistance as measured over the
specified analog signal ranges; i.e., V
NO
= 3V to 0V and 0V to -3V.
Note 5: Leakage parameters are 100% tested at maximum-rated hot operating temperature, and guaranteed by correlation at
T
A
= +25°C.
Note 6: Guaranteed by design, not production tested.
