ALTERNATIVE ANALOG INPUT DRIVE
CONFIGURATION
This section provides a brief description of the alternative analog
input drive configuration using the AD8352. When using this
drive option, some additional components need to be populated.
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 for Channel A. In addition,
the corresponding components for Channel B should be changed.

Remove C1, C17, C18, and C117 in the default analog
input path.
Populate C8 and C9 with 0.1 μF capacitors in the analog
input path. To drive the AD8352 in the differential input
mode populate Transformer T10; Resistors R1, R37, R39,
R126, and R127; and Capacitors C10, C11, and C125.
Populate the optional amplifier output path with the
desired components, including an optional low-pass filter.
Install 0 Ω Resistors R44 and R48. Resistors R43 and R47
should be increased (typically to 100 Ω) to increase the
output impedance seen by the AD8352 to 200 Ω.
