7.9 Off Isolation

Off isolation is defined as the voltage at the drain pin (D, DA, or DB) of the MUX50x when a 1-VRMS signal is

applied to the source pin (Sx, SxA, or SxB) of an off-channel. Figure 33 shows the setup used to measure off

isolation. Use Equation 2 to compute off isolation.

7.10 Channel-to-Channel Crosstalk

Channel-to-channel crosstalk is defined as the voltage at the source pin (Sx, SxA, or SxB) of an off-channel,

when a 1-VRMS signal is applied at the source pin of an on-channel. Figure 34 shows the setup used to measure

channel-to-channel crosstalk. Use Equation 3 to compute, channel-to-channel crosstalk.
