This manual provides instructions for using the EVAL-AD5780 evaluation board. EVAL-AD5780 is a full featured evaluation board designed to allow the user to easily evaluate all features of the AD5780 voltage output, 18-bit digital-to-analog converter (DAC). The EVAL-AD5780 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 AD5780 evaluation software.
This document is the User Guide (UG-256) for the EV-AD5780, a full-featured evaluation board designed for the AD5780 18-bit serial input, voltage output DAC with integrated precision reference buffer amplifiers. The board allows users to easily evaluate all features of the AD5780 and provides accessible pins for external connections.
The positive analog supply must be between 7.5 V and 16.5 V connected between the VDD and AGND inputs.
By default, the board is configured for a ±10 V output range using +10 V and −10 V reference voltages.
A measurement requiring 262,144 points takes approximately 6 hours to complete.
