PARAMETER MEASUREMENT INFORMATION (continued)
Figure 9. Test Circuit for OFF Isolation (O
IRR
)
OFF isolation is measured at the output of the OFF channel. For example, when V
SEL
= GND and A
1
is the input,
the output is measured at 1B
2
. All unused analog input (A) ports are connected to ground, and output (B) ports
are left open.
