Figure 8. Test Circuit for Off Isolation (OIRR)
Off isolation is measured at the output of the OFF channel. For example, when VIN = VCC, VEN = 0, and DA is the
input, the output is measured at S1A. All unused analog input (D) ports are left open, and output (S) ports are
connected to GND through 50-Ω pulldown resistors.
