GENERAL DESCRIPTION
The EVAL-AD5791 is a full-featured evaluation board, designed
to allow the user to easily evaluate all features of the

voltage output, 20-bit DAC. The AD5791 pins are accessible at
on-board connectors for external connection. The board can be
controlled by two means, via the on-board connector (J6) or
via the system development platform connector (J3). The SDP
board allows the evaluation board to be controlled through
the USB port of a Windows® XP (SP2 or later) or Vista (32-bit)
based PC using the AD5791 evaluation software.
DEVICE DESCRIPTION
The AD5791 is a high precision, 20-bit digital-to-analog
converter (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.
