The HI5703EVAL evaluation board can be used to evaluatethe performance of the HI5746 10-bit 40 MSPS analog-todigitalconverter (ADC). The HI5703EVAL evaluation boardis made electrically compliant with the HI5746 by making asimple resistor change in the reference voltage generationcircuits allowing the former +3.25V reference generator circuitto be adjustable to +2.5V.As shown in the HI5703EVAL Evaluation Board (Modified)Block Diagram, the evaluation board includes clock drivercircuitry, reference voltage generators (modified), and achoice of analog input drive circuits. Buffered digital dataoutputs are conveniently provided for easy interfacing to aribbon connector or logic probes. The evaluation board isprovided with some prototyping area for the addition of userdesigned custom interfaces or circuits. Additionally, theevaluation board is provided with eight removable jumpersto allow for various operational configurations. Refer toAN9534, “Using the HI5703 Evaluation Board”, for a completetechnical discussion on the evaluation board.
