Text in bold refers to items directly from the EV kit software. Text in bold and underlined 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 positions, 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 running 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 connecting 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. Table 1.

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. *Default position. __________________________________________________________________ Maxim Integrated Products 3 MAX5216 Evaluation Kit Evaluates: MAX5214/MAX5216 Detailed Description of Software The main window of the MAX5216 EV kit software displays the DAC code and output voltage. Other features include changing the operating modes and reference. 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. 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). Figure 1. MAX5216 EV Kit Part Selection Window Figure 2. MAX5216 EV Kit Software Main Window __________________________________________________________________ Maxim Integrated Products 4 MAX5216 Evaluation Kit Evaluates: MAX5214/MAX5216 Setting the Reference The reference is set to 3.3V by default. Uncheck the Default REF checkbox and enter the new reference voltage 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. Figure 3.

Advanced SPI User Interface Window (3-Wire Interface Tab) 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 connection 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 position. 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. __________________________________________________________________ Maxim Integrated Products 6 MAX5216 Evaluation Kit Evaluates: MAX5214/MAX5216 Figure 5a.
