CXA1386P/K

8bit 75MSPS ADC and DAC Evaluation Board

It is necessary to equip "the CXA1396D/P EVALUATION BOARD WITH DAC" with "A1396D – A1386P

ADAPTER" in order to evaluate CXA1386P.

In addition to indispensable features such as the reference voltage generator, this tool equips two sets of

analog inputs (the direct input and the buffer amplifier input), the input voltage offset generator, the clock

decimator, the output data latches, the 10-bit high-speed DAC, and the 20-pin cable connector for digital

outputs. This evaluation board provides full performance of the CXA1386P and it is designed to facilitate

evaluation.
