EVALUATION BOARD DESCRIPTION 
The EVAL-AD5764R is a full-featured evaluation board 
designed to allow the user to easily evaluate all features of the 
 quad-channel, 16-bit DAC. All of the AD5764R 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 AD5764R evaluation software. The default setup is for 
control via the USB port. 
DEVICE DESCRIPTION 
The AD5764R has a nominal output voltage span of ±10 V 
derived from an internal 10 ppm/°C 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 AD5764R 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 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 AD5764R are available in the 
AD5764R data sheet available from Analog Devices, Inc., and 
should be consulted in conjunction with this data sheet when 
using the evaluation board.
