Product Details
User guide UG-1152 supports the EVAL-AD5791SDZ evaluation board, Revision B. User guide UG-185 supports previous revisions of the evaluation board.The EVAL-AD5791SDZ is a full-featured evaluation board, designed for users to easily evaluate all features of the AD5791 voltage output, 20-bit digital-to-analog converter (DAC). The AD5791 pins are accessible at on-board connectors for external connection. The evaluation board can be controlled by two means: via the on-board connector (J12) or via the system demonstration platform (SDP) connector (J14).
The evaluation board also integrates a power solution utilizing the ADP5070 switching regulator and linear regulators (ADP7118 and ADP7182) to generate a bipolar supply of up to −15 V and +15 V from a +3.3 V single supply. Alternatively, the DAC can be supplied with linear power supplies via the on-board connectors (J11 and J13).
A daughter board connected to the top right of the EVAL-AD5791SDZ includes a voltage reference to externally apply to the DAC.
The EVAL-SDP-CB1Z SDP board allows the EVAL-AD5791SDZ evaluation board to be controlled through the USB port of a Windows®-based PC featuring Windows XP or later when using the AD5791 evaluation software.
The AD5791 is a high precision, 20-bit DAC, designed to meet the requirements of precision control applications. The output range of the AD5791 is configured by two reference voltage inputs. The device is specified to operate with a dual power supply of up to 33 V.
Complete specifications for the AD5791 are available in the AD5791 data sheet available from Analog Devices, which should be consulted in conjunction with this user guide when using the evaluation board.
