Quick Start
Required Equipment
• MAX5216 EV kit (USB cable included)
• Windows XP, Windows Vista, or Windows 7 PC with
a spare USB port
• Digital voltmeter (DVM)
Note: In the following sections, software-related items
are identified by bolding. Text in bold refers to items
directly from the EV kit software. Text in bold and under-
lined refers to items from the Windows operating system.
Procedure
The EV kit is fully assembled and tested. Follow the steps
below to verify board operation:
1) Verify that jumpers JU1–JU6 are in their default posi-
tions, as shown in Table 1.
2) Visit www.maxim-ic.com/evkitsoftware to download
the latest version of the EV kit software, 5216Rxx.ZIP.
Save the EV kit software to a temporary folder and
uncompress the ZIP file.
3) Install the EV kit software on your computer by run-
ning the INSTALL.EXE program inside the temporary
folder. The program files are copied to your PC and
icons are created in the Windows Start | Programs
menu. During software installation, some versions of
Windows may show a warning message indicating
that this software is from an unknown publisher. This
is not an error condition and it is safe to proceed with
installation. Administrator privileges are required to
install the USB device driver on Windows.
4) Connect the USB cable from the PC to the EV kit
board. A Windows message appears when connect-
ing the EV kit board to the PC for the first time. Each
version of Windows has a slightly different message.
If you see a Windows message stating ready to use,
then proceed to the next step. Otherwise, open the
USB_Driver_Help_200.PDF document in the Windows
Start | Programs menu to verify that the USB driver
was installed successfully.
5) Start the EV kit software by opening its icon in the
Start | Programs menu. The EV kit software (Figure
1) prompts the user to select the installed part on the
the EV kit. Once selected, the EV kit software main
window appears (Figure 2).
6) Enter the desired code in the edit box and press the
Enter button or move the scroll bar within the DAC
group box.
7) Using the DVM, measure the voltage at H2-1 (the
OUT pin of the DAC). Verify that the voltage is also
displayed at the bottom of the main software window.

JU2 1-2* Connects the CS pin of the DAC to the on-board microcontroller.
2-3 Connects the CS pin of the DAC to a user-supplied CS signal.
JU3 1-2* Connects the SCLK pin of the DAC to the on-board microcontroller.
2-3 Connects the SCLK pin of the DAC to a user-supplied SCLK signal.
JU4 1-2* Connects the DIN pin of the DAC to the on-board microcontroller.
2-3 Connects the DIN pin of the DAC to a user-supplied DIN signal.
JU5 1-2* Connects the CLR pin of the DAC to the on-board microcontroller.
2-3 Connects the CLR pin of the DAC to a user-supplied CLR signal.
JU6 1-2* Connects the REF pin of the DAC to the voltage at VDD.
2-3 Connects the REF pin of the DAC to the on-board MAX6133 voltage reference.

Detailed Description of Software
The main window of the MAX5216 EV kit software dis-
plays the DAC code and output voltage. Other features
include changing the operating modes and reference.
16-Bit and 14-Bit Part Selection
When the program first starts up, the user must select the
correct part installed on the EV kit (Figure 1). Once the
selection has been made, press the Enter button and the
main software window appears (Figure 2).
Operation
Within the Operation group box, the user can select
between No Operation, Write, and Power Down. Select
the Write radio button when writing to the DAC. Select
the Power Down radio button and the Power Down
Mode group box appears (Figure 3).
DAC Output
The user can enter or scroll to the desired code within
the DAC group box and press Enter. The DAC code and
output voltage appear at the bottom of the software’s
main window.

Setting the Reference
The reference is set to 3.3V by default. Uncheck the
Default REF checkbox and enter the new reference volt-
age in the corresponding edit box. The user must apply
the same voltage at the board for proper operation (see
the Reference section). The voltage entered in the edit
box does not affect the operation of the part.
CLEAR (CLR)
Press the CLEAR button to drive CLR low and reset the
DAC code to 0.

Advanced User Interface
A serial interface can be used by advanced users by
clicking Options | Interface (Advance Users). Click on
the 3-wire interface tab shown in Figure 4. Enter data
into the Data bytes to be written edit box and press the
Send Now button.
Detailed Description of Hardware
The MAX5216 EV kit provides a proven layout for the
MAX5216 16-bit low-power, high-performance, buffered
DAC. An on-board reference (MAX6133), USB-PC con-
nection circuitry, and jumpers to disconnect the on-board
microcontroller are included on the EV kit.
Reference
The EV kit default configuration is with the reference
connected to VDD (see Table 1). To use the on-board
external 2.5V reference (MAX6133), move the shunt on
jumper JU6 to the 2-3 position and apply 2.7V to 12.6V
between the REF_SUP and GND PCB pads on the EV
kit. Optionally, the shunt on JU6 can be removed and an
external 2V to VDD reference applied at the REF loop on
the EV kit.
User-Supplied SPI Interface
and Power Supply
To use the EV kit with a user-supplied SPI interface, first
move the shunts on jumpers JU1–JU5 to the 2-3 posi-
tion. Next, apply a 2.7V to 5.25V power supply at the
EXT_VDD PCB pad on the EV kit. Lastly, connect the CS,
SCLK, DIN, CLR, and GND signals to the corresponding
pins of header H3.
