MAX5216DACLite Evaluation Kit
General Description
The MAX5216DACLite evaluation kit (EV kit) enables
evaluation of the MAX5216 single-channel, low-power,
buffered-output, 3-wire SPI interface, 16-bit DAC. The EV
kit also includes Windows XPM-, Windows VistaM-, and
WindowsM 7-compatible software that provide a simple
graphical user interface (GUI) for exercising the features
of the IC.
The EV kit enables a quick evaluation of the device, with
a fixed supply voltage of 3.3V. The EV kit allows for the
generation of selectable waveforms to display DAC AC
signal-generation capability.
The EV kit can be used as a system hardware debugging
tool, or as a signal generator demonstration kit.

Quick Start
Required Equipment
● MAX5216DACLite EV kit
● The EV kit board is a plug-n-play device that connects to the PC through a USB-A to Mini-B cable. The
cable is not included, but is widely available from local
stores.
● The EV kit is preloaded with the default firmware that
communicates with the MAX5216DACLite evaluation
software. Software can be installed and run on any
Windows-based system.
● Digital multimeter (DMM)
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 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) Visit www.maximintegrated.com/evkitsoftware to
download the latest version of the EV kit software,
5216DACLiteRxx-LV.ZIP. Unzip the file and run the
setup.exe. Follow the instructions to install the evaluation software on your PC. The program files are copied
and icons are created in the Windows Start | Programs
menu. Connect the MAX5216DACLite to the PC though
a USB cable. No additional driver is needed; Windows
recognizes the new device as a human interface
device (HID) and automatically finds and installs the
appropriate driver for it. For more information, check
the device properties in: Device Manager\Human
Interface Control\USB Input Device\Properties →
USB\VID_0B6A&PID_1234. See Figure 1.
2) Run the MAX5216DACLite.exe program. The application’s GUI appears, as shown in Figure 2.

Detailed Description of Software
Single Operation Tab
The Single Operation tab sheet (Figure 2) is active by
default. The application checks all the boards with the
USB VID/PID 0x0B6A/0x1234 that connected to the PC
and indicates them on the right side of the GUI. Up to 16
boards can be connected to the system. Each board has
its own unique board index. Select the appropriate board
index in the Board Index spin box (Figure 3).
Any possible operation can be evaluated on this tab
sheet. For example, move the track bar slider to set the
DAC output voltage. The DAC Control spin box reflects
the slider position with a decimal number. Connect the
DMM to the J5 header (Figure 8) to measure the DAC
output voltage.
MAX5216DACLite Evaluation Kit
The DAC output can also be set by typing in a decimal,
hexadecimal, or an octal or binary value in the DAC
Control spin box (Figure 4). The IC accepts codes from
0 to 65535 (216-1) decimal or from 0 to FFFF hex. The
notation is displayed on the left side of the box.
The Rising Ramp, Falling Ramp, Triangle, Sine,
Square wave, or Staircase tab sheets give the DAC the
ability to generate different waveforms with the selected
parameters (see the sine-wave and staircase plots in
Figures 5 and 6). There is a possible delay to start a new
waveform until the previous one finishes a full cycle when
switching between tabs. It is recommended to stop running the application, select the next tab, and run it again.

Detailed Description of Hardware
The MAX5216DACLite EV kit board is loaded with the
MAX5216, Maxim’s best-in-class, lowest power, 16-bit
DAC. The on-board MAX6133A30 provides low noise, low
temperature drift of 3ppm/°C, and 3.000V precise voltage
reference for the DAC. The MAX5216 (U1) receives a
command from the 16-bit MAXQ622 microcontroller (U2)
through a 3-wire high-speed SPI bus. The U1 device can
run at 50MHz clock frequency, but the SPI bus speed
is limited to 6MHz on this board by the microcontroller.
The U1–U3 devices are powered by the MAX8510 +3.3V
LDO, low-noise voltage regulator (U4), which gets power
from the USB port. The U1 device can be evaluated at
the fixed VDD level of 3.3V only. The above limitations are
reflected by the suffix “Lite” in the name of the board. The
EV kit block diagram is shown in Figure 7.

The evaluation software allows full access to the DAC’s
functions and features through the full-speed USB 2.0
bus and the U2 microcontroller. The microcontroller is
preloaded with firmware that communicates with the GUI.
MAX5216Lite Extended Features
The U1 device can be evaluated over the full voltage and
SPI bus speed range with external power supply and SPI
host controller. To do so, the following board modifications
must be made:
1) Totally disconnect the U1 and U3 devices from the rest
of the board by removing resistors R4–R9 (see Figure 10
for component placement).
2) Connect the SPI lines (CSb, SCLK, DIN, and CLRb
pins) from J6 to the external host controller. Make sure
that the input voltage (VIH) is within the spec limit and
matches the AVDD level.
3) Apply external power from 2.7V to 5.5V between J3.2
(AVDD) and J8 (GND).
MAX5216DACLite Evaluation Kit
The microcontroller on the EV kit board can also be
programmed with custom firmware through the J2 JTAG
connector (see Table 1).
