EVALUATION BOARD DESCRIPTION

The EVAL-AD5760 is a full-featured evaluation board designed
to allow the user to easily evaluate all features of the
voltage output, 16-bit digital-to-analog converter (DAC). The
AD5760
pins are accessible at on-board connectors for external
connection. The board can be controlled by two means: via the
on-board connector (J3), or via the system demonstration (SDP)
platform connector (J4). The SDP board allows the evaluation
board to be controlled through the USB port of a Windows®
XP-based (SP2 or later) or Vista-based (32-bit) computer using
the
AD5760
evaluation software.

DEVICE DESCRIPTION

The
AD5760
is a high precision, 16-bit DAC with integrated
precision reference buffer amplifiers designed to meet the
requirements of precision control applications. The output
range of the
AD5760
is configured by two reference voltage
inputs. The device is specified to operate with a dual power
supply of up to 33 V.
