Description
The HI5728EVAL1 evaluation board provides a quick and easy method for evaluating the HI5728, 125MSPS Dual High Speed DAC. Each converter outputs a current into a load resistor to form a voltage which can be measured by using the included SMA connectors. The amount of current out of the DAC is determined by an external resistor and either an internal or external reference voltage. The evaluation board also includes a VME digital interface that is compatible with the HSP-EVAL board, so DDS (Direct Digital Synthesis) can be performed with minimal setup time. A transformer is included to take advantage of differential signal drive.
