MAX5217 Evaluation Kit
Detailed Description of Software
The MAX5217 EV kit software controls the DAC code
and output voltage. Other features include changing the
operating modes and reference.
Part Selection
In the upper-left corner of the GUI is a Part Selection
group box. The user must select the appropriate radio
button that corresponds to the installed Maxim IC DAC
bits.
I
The software automatically detects the correct I
address from the drop-down list. See Table 2 for a list of
the I
Reference
When setting the reference, confirm that the VDD supply
is greater or equal to the voltage reference entered for
proper operation. To use the external reference, the user
must enter a valid voltage in the REF edit box.
Command
Choose the appropriate Command from the drop-down
list and drag the Data scrollbar to start writing data.
Optionally, the user can enter the desired data in the
Data edit box and press the Enter key on the keyboard.
Refer to the MAX5215/MAX5217 IC data sheet for a list of
possible commands.
Software Reset
The SW Reset button allows the user to reset the
CODE register, the DAC latch, and all the configuration
commands to the POR default values.
Software Clear
The SW Clear button allows the user to clear the CODE
register and the DAC latch to the clear value selected in
the Clear Value group box.

Configuration
The Configuration group box includes the controls to the
configuration register: clear values, AUX input mode, and
power-down mode of the device.
Clear Values
The user can set the DAC values to zero, mid scale, or full
scale when the SW Clear button is pressed.
AUX Pin
The user can use the AUX pin for LDAC and CLR
operations. Once the appropriate selection is made, the
AUX pin can be driven high, low, or pulsed. Refer to the
MAX5215/MAX5217 IC data sheet for a detailed descrip-
tion of AUX pin functions.
DAC Outputs
When the output of the DAC is not in normal operation,
the output can be powered down with a 1kΩ termination
to GND, 100kΩ termination to GND, or high impedance.
Read Back
The product ID is read when an address is detected.
Within the DAC group box, press the Read Back button
and the code and voltage of the DAC are displayed.
Within the Configuration group box, press the Read
Back button and the clear values, AUX pin, and DAC
outputs are read back.
Multiple EV Kits
The software can communicate to multiple MAX5217 EV
kits connected to the USB ports on the PC. The status
bar at the bottom of the GUI shows the number of boards
that are connected. If all boards connected to the PC are
not connected to the GUI, click the Connect menu item
and the status bar should be updated. Use the Board
Index drop-down list to select the appropriate EV kit for
communication.
