ALTERNATIVE ANALOG INPUT DRIVE
CONFIGURATION
The following is a brief description of the alternative analog input
drive configuration using the
option is in use, some components may need to be populated, in
which case all the necessary components are listed in Table 17. For
more details on the AD8332 dual VGA, including how it works
and its optional pin settings, consult the AD8332 data sheet.
To configure the analog input to drive the VGA instead of the
default transformer option, the following components need to
be removed and/or changed.

Remove R102, R115, R128, R141, R161, R162, R163, R164,
T101, T102, T103, and T104 in the default analog input path.
Populate R101, R114, R127, and R140 with 0 Ω resistors in
the analog input path.

In this configuration, L301 to L308 and L401 to L408 are
populated with 0 Ω resistors to allow signal connection and use
of a filter if additional requirements are necessary.
Populate R105, R113, R118, R124, R131, R137, R151, and
R160 with 0 Ω resistors in the analog input path to connect
the AD8332.
Populate R152, R153, R154, R155, R156, R157, R158, R159,
C103, C105, C110, C112, C117, C119, C124, and C126
with 10 kΩ resistors to provide an input common-mode
level to the ADC analog inputs.
Remove R305, R306, R313, R314, R405, R406, R412, and
R424 to configure the AD8332.
