Figure 11. Test Circuit for OFF Isolation (O_IRR)
The OFF isolation is measured at the output of the OFF channel. For example, when V_IN = V_CC, V_EN = 0, and
D_A is the input, the output is measured at S1_A. All unused analog input (D) ports are left open, and output (S) ports
are connected to GND through 50-Ω pulldown resistors.
