Note 2: The algebraic convention is used in this data sheet; the most negative value is shown in the minimum column.
Note 3: Devices are tested at maximum hot temperature and are guaranteed by design and correlation at TA = +25°C and -40°C
specifications.
Note 4: RON and ∆RON matching specifications for thin QFN-packaged parts are guaranteed by design.
Note 5: ∆RON = RON(MAX) - RON(MIN).
Note 6: Flatness is defined as the difference between the maximum and minimum value of on-resistance as measured over the
specified analog signal ranges.
Note 7: Guaranteed by design; not production tested.
Note 8: Off-isolation = 20log10(VCOM_ / VNO), VCOM_ = output, VNO = input to off switch.
Note 9: Between any two channels.
