INTRODUCTION
This evaluation board is for the AD5380, AD5381, AD5382, and
AD5383, 32-/40-channel, 12-/14-bit DACs. The AD538x parts
contain 32/40, 12-/14-bit DACs in one package. They have a
maximum output voltage span of 5 V derived from a reference
voltage of 2.5 V.
The AD538x parts have a parallel interface in which 12/14 data
bits are loaded into one of the input registers under the control
of the WR , CS , and DAC channel address pins, A0 to A5. They
also have a 2-wire I
which are compatible with SPI®, QSPI™, MICROWIRE™, and
DSP interface standards.
The DAC outputs are updated when the DAC registers receive
new data. All the outputs can be updated simultaneously by
taking the LDAC input low.

product details.
AD538x EVALUATION BOARD POWER SUPPLIES
The following external supplies must be provided:
Both AGND and DGND inputs are provided on the board. The
AGND and DGND planes are connected at one location close
to the AD538x. Avoid connecting AGND and DGND elsewhere
in the system to avoid ground loop problems.
Each supply is decoupled to the relevant ground plane with
47 µF and 0.1 µF capacitors. Each device supply pin is again
decoupled with a 10 µF and 0.1 µF capacitor pair to the relevant
ground plane.
