LFCSP Evaluation Board

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.

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).
