PARAMETER MEASUREMENT INFORMATION (continued)
Figure 7. Test Circuit for Frequency Response, Crosstalk, and OFF-Isolation
The frequency response is measured at the output of the ON channel. For example, when V
IN
= 0, V
EN
= 0, and
D
A
is the input, the output is measured at S
1A
. All unused analog I/O ports are held at V
CC
or GND.
The crosstalk is measured at the output of the non-adjacent ON channel. For example, when V
IN
= 0, V
EN
= 0,
and D
A
is the input, the output is measured at S
1B
. All unused analog I/O ports are held at V
CC
or GND.
The off-isolation is measured at the output of the OFF channel. For example, when V
IN
= 0, V
EN
= V
CC
, and D
A
is
the input, the output is measured at S
1A
. All unused analog I/O ports are held at V
CC
or GND.
