The MAX1241 evaluation kit (EV kit) is an assembled
and tested PC board that demonstrates the 3V, 12-bit
MAX1241 analog-to-digital converter.
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
provides a handy user interface to exercise the
MAX1241’s features. Source code is provided.
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.
