EVALUATION BOARD DESCRIPTION
The EVAL-AD5780 is a full-featured evaluation board, designed
to allow the user to easily evaluate all features of the
to allow the user to easily evaluate all features of the
voltage output, 18-bit digital-to-analog converter (DAC). The
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 development platform
connector (J4). The SDP board allows the evaluation board to be
controlled through the USB port of a Windows® XP- (SP2 or later)
or Vista-based (32-bit) PC using the
