GENERAL DESCRIPTION
This data sheet describes the evaluation board for the
quad, 16-bit DAC. The AD5665R 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 for the use of an external reference (the
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 for the use of an external reference (the
on this
evaluation board). The part must be written to after power-up
to turn on the internal reference.
