AD9235
LFCSP EVALUATION BOARD
The typical bench setup used to evaluate the ac performance
of the AD9235 is similar to the TSSOP Evaluation Board
connections (refer to the schematics for connection details).
The AD9235 can be driven single-ended or differentially
through a transformer. Separate power pins are provided to
isolate the DUT from the support circuitry. Each input
configuration can be selected by proper connection of
various jumpers (refer to the schematics).

An alternative differential analog input path using an AD8351
op amp is included in the layout but is not populated in produc-
tion. Designers interested in evaluating the op amp with the
ADC should remove C15, R12, and R3 and populate the op amp
circuit. The passive network between the AD8351 outputs and
the AD9235 allows the user to optimize the frequency response
of the op amp for the application.
