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 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. For
Channel B the corresponding components 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 the T10 transformer; the R1, R37, R39,
R126, and R127 resistors; and the C10, C11, and C125
capacitors.
Populate the optional amplifier output path with the
desired components including an optional low-pass filter.
Install 0 Ω resistors, R44 and R48. R43 and R47 should be
increased (typically to 100 Ω) to increase to 200 Ω the
output impedance seen by the AD8352.
