MAX9959 Evaluation Kit
Evaluates: MAX9959
Quick Start
Required Equipment
• MAX9959 EV kit (USB cable included)
• User-supplied Windows 2000/XP or Windows Vista
PC with a spare USB port
• ±12V, 2A power supply
• Two digital voltmeters
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.
an error condition and it is safe to proceed with
installation. Refer to the USB_Driver_Help.PDF doc-
ument included with the software for additional
information.
6) Apply +12V to VCC (P2) and -12V to VEE (P4).
7) Start the MAX9959 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.
8) In the
MAX9959 Settings
group box, click on the
FV
radio button in the
Set Measurement Mode
group box.
9) In the
MAX5735 Settings
group box, change the
voltage for
VIN
to +1V.
10) Check that the output voltage at DUT_NODE_M
(P8) is close to +1V. Figure 2 shows the MAX9959
EV kit quick start settings.
Procedure
The MAX9959 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,
9959Rxx.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 are in their default positions,
as shown in Table 1.
4) Connect the USB cable from the PC to the EV kit
board. A
New Hardware Found
window pops up
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 30 seconds, remove the USB
cable from the board and reconnect it.
Administrator privileges are required to install the
USB device driver on Windows.
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\MAX9959
(default installation
directory) using the
Browse
button. During device
driver installation, Windows may show a warning
message indicating that the device driver Maxim
uses does not contain a digital signature. This is not
Detailed Description of Software
The main window of the evaluation kit software is
shown in Figure 1.
MAX9959 Settings
The MAX9959 supports an 18-bit word SPI interface. The
GUI provides a simple way to correlate setting changes
with bit settings. There are two on-board MAX9959
devices connected in a daisy-chain configuration. U1
can be considered the
Master
and is denoted with an
_M in the schematic, U2 can be considered the
Slave
and is denoted with an _S in the schematic, but both
devices can be programmed to operate independently.
Because of the daisy-chain configuration, the bit stream
for U2 goes through U1 first. To avoid accidental pro-
gramming of a device when communicating with another
device in the daisy chain, bit 0 masks writing to the
MAX9959 and bit 1 masks the loading of the settings.
Both bits are automatically updated when using
Master
and
Master1/Master2
modes. The default setting by the
GUI is
Manual Control
and allows the user to set all
settings independently. Selecting
Master, Master/
Slave,
or
Master1/Master2
forces certain bit settings
that are required for that mode.
The
Set Measurement Mode
group box is a quick way
to set the MAX9959 to force voltage (FV), force current
(FI), force current as a slave device (FI
Slave),
or place
into high impedance (Hi-Z). Bit settings are automati-
cally changed to match mode settings.

Figure 1. MAX9959 EV Kit Software Main Window at Startup
MAX5735 Settings
The MAX5735 outputs voltages for both MAX9959
devices. The output voltages are set by moving the
scrollbars located in the
MAX5735 Settings
group box
or by entering data in the corresponding edit boxes
and pressing
Enter
on the keyboard. The edit boxes
accept the value of the voltage or binary code.
Changes in the
DC Level
edit boxes automatically
change the values in the
DAC Setting
edit boxes and
vice versa. The min and max values allowed for each
analog voltage setting set their scrollbar ranges.
Analog voltages (VIN,
IOSI, IOSV, CLH, CLL, ITHHI,
and
ITHLO)
are set by the MAX5735 and appear as the
input levels for the MAX9959. The MAX5735 has two
tabs (Device
1
and
Device 2)
to change the analog
input voltages for both MAX9959 devices.
MAX531 Settings
The MAX531 can be used for calibration by shifting the
GND sense on the MAX5735. The GND shift on the
MAX5735 should not exceed ±0.5V and the
GND
Offset
scrollbar inside the
MAX531 Settings
group box
is limited to that range.
AutoWrite
The
AutoWrite
checkboxes can be checked to have
the software automatically perform write operations.
This feature allows the user to change settings and
have them updated without pressing the
WRITE
but-
tons. There is an
AutoWrite
checkbox for writing to the
MAX9959, MAX5735, and MAX531. Each device can
independently perform auto writing.
AutoWrite
is
enabled by default.
