EVAL-AD5767SD2Z FEATURES

Full featured evaluation board for the AD5767 with theADP5071 power solutionPC control in conjunction with the Analog Devices, Inc.,EVAL-SDP-CB1Z system demonstration platform (SDP)Power solution generated from a single 3.3 V supplyPC software for control using analysis/control/evaluation(ACE) software

EVAL-AD5767SD2Z GENERAL DESCRIPTION

The EVAL-AD5767SD2Z is a fully featured evaluation board thatallows the user to easily evaluate all the features of the AD576716-channel, 12-bit, voltage output digital-to-analog converter(DAC).This board also integrates a power solution using the ADP5071switching regulator to generate a bipolar supply of +8 V and−22 V from a +3.3 V input, allowing a DAC voltage outputrange of −20 V to +6 V. Alternatively, supplying the DAC with alinear power supply via the on-board connector (J9) achieves allranges.The AD5767 can be controlled using the on-board connector(J10) or the EVAL-SDP-CB1Z SDP board (via J1). The SDPallows the evaluation board to be controlled through the USBport of a Windows®-based PC using the AD5767 evaluationsoftware.The AD5767 is a 16-channel, 12-bit voltage output denseDAC®.The DAC generates output ranges from a 2.5 V reference. TheAD5767 also integrates output buffers allowing the device tosource or sink up to 20 mA. The range is software selectable,and any channel can be routed to the monitor pin for externalmonitoring. The integration of the reference and output buffersallows an easy to use universal solution.The device requires four power supplies. AVDD and AVSS are thepositive and negative high voltage power supplies, AVCC is theanalog supply for the low voltage DAC circuitry, and a VLOGICsupply pin sets the logic levels for the digital interface pins.The ACE software provides an intuitive graphic user interface(GUI), allowing all of the AD5767 modes of operation to beconfigured over the synchronous serial port (SPORT) interface.The ACE software also has plugin modules for many otherAnalog Devices evaluation boards and Circuits from the Lab®(CFTL) demo boards.Complete specifications for the AD5767 are available in theAD5767 data sheet, which must be consulted in conjunctionwith this user guide when using this evaluation board.
