GENERAL DESCRIPTION
The Analog Devices, Inc., AD5668 evaluation board (EVAL-
AD5668EBRZ and AD5668EBCZ) is designed to help
customers quickly prototype new AD5668 circuits and reduce
design time. The AD5668 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 allowing
for the use of an external reference; the REF195 is used on this
evaluation board. The part must be written to after power-up to
turn on the internal reference.
