(1)
The algebraic convention, whereby the most negative value is a minimum and the most positive value is a maximum.
(2)
Parts are tested at 85
°C and specified by design and correlation over the full temperature range.
(3)
Typical values are at TA = 25°C.
(4)
r
on = ron(max) – ron(min)
(5)
Flatness is defined as the difference between the maximum and minimum value of ron as measured over the specified analog signal
ranges.
(6)
Leakage parameters are 100% tested at the maximum-rated hot operating temperature and specified by correlation at TA = 25°C.
(7)
OFF isolation = 20log10 (VCOM/VNO), VCOM = output, VNO = input to OFF switch
