Product
Demonstration Boards
The MAX6946 evaluation (EV) kit is an assembled and
tested PCB that demonstrates the capabilities of the
MAX6946 constant-current LED driver and digital I/O
expander. The EV kit includes three RGB LEDs and one
white LED that can be controlled simultaneously by the
MAX6946. The MAX6947 can also be evaluated on the
EV kit board by replacing the MAX6946 IC.
The MAX6946 evaluation system (EV system) includes
a MAX6946 EV kit and a Maxim interface board
(CMAXQUSB). The CMAXQUSB board connects to a
PC’s USB port and allows the transfer of I
to the MAX6946 EV kit.
The CMAXQUSB board allows a PC to use its USB port to
emulate
98SE/2000/XP-compatible software (which can be
downloaded from www.maxim-ic.com/evkitsoftware) pro-
vides a user-friendly interface to exercise the fea-
tures of the MAX6946. The program is menu driven and
offers a graphical user interface (GUI) with control buttons
and a status display. Order the MAX6946EVCMAXQU+
for a complete PC-based evaluation kit of the MAX6946.
Order the MAX6946EVKIT+ if you already have a
CMAXQUSB interface board or an I
interface system.
