Input Register
The Input Register section displays the current contents of the
input register; the 24-bit display is updated each time you
instruct a read or a write operation.

Control Register
The Control Register section allows you to program and read
the contents of the control register. The control register consists
of four bits: TSD enable, clamp enable, CLR select, and SDO
disable. Each of these bits is controlled by a toggle button,
which sets the bit high or low; a high bit is indicated by the
button turning blue, while a low bit is indicated by the button
turning white. The control register also contains two functions,

Program Output Voltage
This section allows you to program/read the data registers of
the four DAC channels. A drop-down box allows you to select
hexadecimal or binary coding. To program a data register, click
one of the 16 text boxes (4 text boxes per DAC channel). The
value in the textbox is programmed to the data register;
if a new value is typed into a text box, this value can be pro-
grammed to the data register by pressing the Enter key. The
DAC output updates if the LDAC pin is low or if the Pulse

On-Board ADC
The AD5754R evaluation board is equipped with an on-board
ADC to facilitate measurement and readback of the output
voltages of each DAC channel. At any time, click Measure

on-board ADC has a maximum input voltage range of ±10 V.
Resolution
For the purposes of evaluating the 12-bit (AD5724R) or 14-bit
(AD5734R) versions of the AD5754R, the board can be operated
at 12 or 14 bits of resolution by selecting the appropriate menu
item from the Resolution drop-down menu on the menu bar.
