Quick Start
Recommended Equipment
Before beginning, the following equipment is needed:
• MAX5116 EV kit (USB cable included)
•
•
Voltmeter
A user-supplied Windows 2000/XP/Vista-compatible
PC with a spare USB port
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 MAX5116 EV Kit is fully assembled and tested.
Follow the steps below to verify board operation:
1) Visit
www.maxim-ic.com/evkitsoftware
to down-
load the latest version of the EV kit software,
5116Rxx.ZIP. Save the EV kit software to a tempo-
rary folder and uncompress the ZIP file.
2) Install the EV kit software on your computer by run-
ning the INSTALL.EXE program inside the tempo-
rary folder. The program files are copied and icons
are created in the Windows
Start | Programs
menu.
3) Verify that all jumpers (JU1–JU12) are in their
default positions, as shown in Table 1.
4) Connect the USB cable from the PC to the EV kit
board. A
Building Driver Database
window pops
up in addition to a
New Hardware Found
message
when installing the USB driver for the first time. If
you do not see a window that is similar to the one
described above after 30s, remove the USB cable
from the board and reconnect it. Administrator privi-
leges are required to install the USB device driver
on Windows 2000/XP/Vista. Refer to the
USB_Driver_Help.PDF document included with the
software if you have any problems during this step.
5) Follow the directions of the
Add New Hardware
Wizard
to install the USB device driver. Choose the
Search for the best driver for your device
option.
Specify the location of the device driver to be
C:\Program Files\MAX5116
(default installation direc-
tory) using the
Browse
button. During device driver
installation, Windows might show a warning message
indicating that the device driver Maxim uses does not
contain a digital signature. This is not an error condi-
tion and it is safe to proceed with installation.
6) Start the MAX5116 EV kit software by opening its
icon in the
Start | Programs
menu. The EV kit soft-
ware main window appears, as shown in Figure 1.

7) Wait approximately 5s for the program to automati-
cally detect the slave address (0x5E) of the
MAX5116 in the
Address
drop-down list.
8) Drag the DAC0 track bar in the
Volatile Register
group box all the way to the right.
9) Use the voltmeter to verify that the voltage on the
OUT0 pad is approximately 2.5V.

Figure 1. MAX5116 EV Kit Software Main Window
Detailed Description of Software
To start the MAX5116 EV kit software, double-click the
MAX5116 EV kit icon that is created during installation.
The GUI main window appears, as shown in Figure 1.
The
DAC
group box located at the left of the window
controls the output-voltage settings for the DACs. Mute
and power-down functions are in the
Mute/Power-
Down
group box located in the middle section. The
Status
group box at the right displays the voltage val-
ues of the DACs. The
I2C Interface
group box at the
top allows the user to transfer I
2
C commands by enter-
ing the commands in the edit boxes.
By default, the MAX5116 is selected in the
Device
drop-
down list. Select MAX5109 in the
Device
drop-down list
when evaluating the MAX5109 using the MAX5116 EV kit.
The I
2
C slave address of the MAX5116 depends on the
jumper settings of JU5–JU8. The
Address
drop-down
list automatically detects the MAX5116’s I
2
C slave
address when the GUI software starts. When the EV kit
is shipped, the default I
2
C slave address is 0x5E. If the
jumper settings of JU5–JU8 change, press the
Auto
Detect Address
button to automatically detect the new
I
2
C slave address of the MAX5116.

DAC
In the
DAC
group box, the user can set the output-
voltage values for the DACs. Measure the actual refer-
ence voltage on the REFH and REFL pins of the
MAX5116 and enter the values into the corresponding
REFH_
and
REFL_
edit boxes. Those values are used
to calculate the expected output-voltage values of the
DACs.
In the
Volatile Registers
group box,
DAC0–DAC3
track bars are used to change the voltage values in the
volatile DAC register of the DACs. The adjacent labels
at the right of the track bars display the equivalent out-
put-voltage values of the DACs. Use the
All DAC
track
bar to send the “Write All VREG” operation that config-
ures DAC0–DAC3 all at the same time.
In the
Nonvolatile Registers
group box, use the
DAC0–DAC3
track bars to change the values in the
nonvolatile register of the DACs.
Similarly, in the
Volatile and Nonvolatile Registers
group box, use the
DAC0–DAC3
track bars to change
the values in both of the volatile and nonvolatile registers.
Press the buttons in the
Transfer DAC NVREG to
VREG
group box to transfer values from the nonvolatile
DAC registers to volatile DAC registers.
Status
In the
Status
group box, press the
Read
button to read
the values from all the volatile and nonvolatile registers.
Values from the volatile and nonvolatile DAC registers
are displayed in the
Volatile DAC Register
and
Non-
Volatile DAC Register
group boxes. Values from the
volatile and nonvolatile mute/power-down registers are
displayed in the
Volatile Mute/Power-Down Register
and
Non-Volatile Mute/Power-Down Register
group
boxes. Check the
Auto Read
checkbox at the top of
the
Status
group box to automatically read the current
values from all registers.

C Interface
In the
I2C Interface
group box, the
Read/Write Status
group box displays the last command and data that are
sent or received from the MAX5116.
The
Read/Write Command
group box allows the user
to manually enter the I
2
C read/write command and data
in the edit boxes and sends them to the MAX5116 by
pressing the
Send Command
button.
Detailed Description of Hardware
The MAX5116 EV kit board provides a proven layout
for evaluating the MAX5116 and MAX5109 ICs. The EV
kit comes with the MAX5116EEE+ installed. The
MAX5116 EV kit can also be used to evaluate the
MAX5109. Contact the factory for free samples of the
MAX5109EEE+ device.
Mute/Power-Down
The
Mute/Power-Down
group box has the mute and
power down controls for the DACs. The
Mute DAC_
buttons are used to mute the DACs. The
Power-down
DAC_
buttons are used to set the DACs in power-
down mode.
In the
Volatile Register
group box, each button corre-
sponds to a bit in the volatile mute/power-down regis-
ter. Press the button to toggle the bit.
In the
Nonvolatile Register
group box, each button
corresponds to a bit in the nonvolatile mute/power-down
register. Press the applicable button to toggle the bit.
Pressing the buttons in the
Volatile and Nonvolatile
Register
group box toggles the bits in both volatile and
nonvolatile registers.
Press the
NVREG >> VREG
button at the bottom of
the
Mute/Power-Down
group box to transfer values
from the nonvolatile mute/power-down register to
volatile register.
Press the
Mute All (/MUTE)
button to toggle the signal
on the
MUTE
pin of the MAX5116.
I
2
C Address Configuration
The combinations of shunt positions for jumpers
JU5–JU8 determine the I
2
C slave address of the
MAX5116 EV kit. Refer to the MAX5116 IC data sheet
for appropriate settings.
Voltage Reference
By default, the on-board MAX6126 2.5V external refer-
ence is connected to the REFH (REFH0**) pin of the
MAX5116, and the REFL (REFL0**) is connected to
ground. Place the shunt of JU9 to the 1-2 position to con-
nect the VDD to the REFH (REFH0**) pin. To use an
external voltage reference, place the shunts of JU9 to the
1-4 position and the shunts of JU8 to the 2-3 position.
Attach the high- and low-voltage references to the REFH
(REFH0**) and REFL (REFL0**) pads. Adjust the REFH
(REFH0**) and REFL (REFL0**) values in the program.
When evaluating the MAX5109, a second pair of volt-
age references (REFH1 and REFL1) is needed. The
jumper settings for the REFH1 and REFL1 are similar to
the settings for the REFH (REFH0**) and REFL
(REFL0**), as previously mentioned.
**Refers
to the MAX5109.
