GENERAL DESCRIPTION
This data sheet describes the evaluation board for the
dual 16-bit DAC. The AD5667R
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-chip reference to give an output voltage span of 2.5 V or 5 V,
respectively. The on-chip reference is off at power-up allowing
on-chip reference to give an output voltage span of 2.5 V or 5 V,
respectively. The on-chip reference is off at power-up allowing
for the use of an external reference (the
on this evalua-
tion board). The part must be written to after power-up to turn
on the internal reference.

Complete specifications for the AD5667R
can be found in the
data sheet available from Analog Devices, Inc., and should be
consulted in conjunction with this data sheet when using the
evaluation board.
