GENERAL DESCRIPTION
The Analog Devices, Inc., AD5669 evaluation board (EVAL-
AD5669REB1Z and AD5669REB2Z) is designed to help
customers quickly prototype new AD5669 circuits and reduce
design time. The AD5669 operates from a single 2.7 V to
5.5 V supply. The part incorporates an internal 1.25 V or 2.5 V
on-board reference to give an output voltage span of 2.5 V or
5 V, respectively. The on-board reference is off at power-up
al l o w i ng f o r t h e u s e o f a n e x t e r n al r e f e r e n c e -----the REF195 is
used on this evaluation board. The part must be written to after
power-up to turn on the internal reference.
Full data on the AD5669 may be found in the data sheet
available from Analog Devices and should be consulted in
conjunction with this data sheet when using the evaluation
board.
The evaluation board interfaces to the USB port of an IBM
compatible PC via the SDP board. Software is available with the
evaluation board which allows the user to easily program the
AD5669.
