LFCSP Evaluation Board
The typical bench setup used to evaluate the ac performance of
the AD9236 is similar to the TSSOP evaluation board
connections. The AD9236 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 (see Figure 48).

An alternative differential analog input path using an AD8351
op amp is included in the layout but is not populated in
production. 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 AD9236 allows the user to optimize the frequency
response of the op amp for their application.
