ALTERNATIVE ANALOG INPUT DRIVE

CONFIGURATION

This section provides a brief description of the alternative

analog input drive configuration using the AD8352 . When

using this particular drive option, some components need to be

populated as listed in Table 16. For more details on the AD8352

differential driver, including how it works and its optional pin

settings, consult the AD8352 data sheet.

To configure the analog input to drive the AD8352 instead of

the default transformer option, the following components need

to be added, removed and/or changed:

•

Remove C1 and C2 in the default analog input path.

•

Populate R3 and R4 with 200 Ω resistors in the analog

input path.

•

Populate the optional amplifier input path with all

components, except R594, R595, and C502. Note that to

terminate the input path, only one of these components,

(R9, R592, or R590 and R591) should be populated.

•

Populate C529 with a 5 pF capacitor in the analog

input path.

Currently, R561 and R562 are populated with 0 Ω resistors to

allow signal connection. This area allows the user to design a

filter if additional requirements are necessary.
