PARAMETER MEASUREMENT INFORMATION (continued)
Figure 10. Test Circuit for Off Isolation (O
IRR
)
OFF isolation is measured at the output of the OFF channel. For example, when V
SEL
= 0 V and A
1
is the input,
the output is measured at 1B
2
. All unused analog input (A) ports are left open, and output (B) ports are
connected to GND through 50-Ω pulldown resistors.
