The MAX1241 evaluation kit (EV kit) is an assembled
and tested PC board that demonstrates the 3V, 12-bit
MAX1241 analog-to-digital converter.
♦ Proven PC Board Layout
♦ Complete Evaluation System
♦ Convenient On-Board Test Points
♦ Data-Logging Software
The MAX1241 evaluation system (EV system) is a com-
plete, low-cost, single-channel data-acquisition system
consisting of a MAX1241 EV kit and a Maxim 3V micro-
controller (µC) module. IBM PC-compatible software
p rovid e s a ha nd y us e r inte rfa c e to e xe rc is e the
MAX1241’s features. Source code is provided.
♦ Source Code Provided
♦ Fully Assembled and Tested
Order the EV system for comprehensive evaluation of
the MAX1241 using a personal computer. Order the EV
kit if you have already purchased the 3V µC module
with another Maxim EV system, or for custom use in
other µC-based systems.

The MAX1241 EV kit evaluates both the MAX1241 and
the MAX1240. To evaluate the MAX1240, order a free
sample of the MAX1240BCPA along with the MAX1241
EV kit.

1) Copy the files from the distribution disk to your hard
disk or to blank floppy disks. The MAX1241 EV kit
software should be in its own directory. The neces-
sary files are in the distribution disk’s root directory,
and the source code is in the SOURCE subdirec-
tory. The SOURCE subdirectory is not required to
operate the EV kit.

4) Connect a 5V DC power source (16V max) to the µC
module. This is located at the terminal block next to
the on/off switch, in the upper-right corner of the µC
module. Observe the polarity marked on the board.
