EVALUATION BOARD DESCRIPTION
The EVAL-AD5764EB is a full-featured evaluation board
designed to allow the user to easily evaluate all features of the
AD5764 quad-channel, 16-bit DAC. All of the AD5764 pins are
accessible at on-board connectors for external connection. The
board can be controlled by two means, via the on-board
connectors or via the USB port of a Windows®-based PC using
the AD5764 evaluation software. The default setup is for control
via the USB port.

DEVICE DESCRIPTION
The AD5764 has a nominal output voltage span of ±10 V
derived from a reference voltage of +5 V. The part also includes
a 3-wire serial interface that is compatible with SPI®, QSPI™,
MICROWIRE™, and DSP interface standards. Data is written to
the AD5764 in a 24-bit word format, and a data output pin
(SDO) is also offered for daisy-chaining or readback.
The DAC outputs are updated upon reception of new data into
the DAC registers. All the outputs can be simultaneously
updated by taking the LDAC input low.
Each channel has a programmable gain and offset adjust
register. Each DAC output is buffered on-chip.
Complete specifications for the AD5764 are available in the
AD5764 data sheet available from Analog Devices, Inc., and
should be consulted in conjunction with this data sheet when
using the evaluation board.
