The MAX7500 evaluation kit (EV kit) is a fully assem-
bled and tested surface-mount PCB that evaluates the
MAX7500 digital temperature sensor. The MAX7500
accurately measures temperature, provides an
overtemperature alarm/interrupt/shutdown output, fea-
tures three address select lines, and integrates a time-
out feature that offers protection against I
lockups.
The EV kit is self-powered from the on-board USB inter-
face and requires no external power. The MAX7500 EV
kit can also evaluate the MAX7501–MAX7504 ICs.
Request free IC samples from the factory when order-
ing the MAX7500 EV kit.

The MAX7500 EV kit provides an on-board I
interface and is connected to the computer through the
USB port. The EV kit includes Windows 2000/XP and
Windows Vista-compatible software that provides a
graphical user interface (GUI) for control of the
MAX7500’s programmable features and selects
between the eight available slave addresses of the
MAX7500 IC.
Jumper JU1 selects between the MAX7500 EV kit’s
power-up options; either on-board through the USB
interface or through an external user-supplied DC power
supply. The voltage from the USB interface is stepped
down to +3.3V through the MAX8512 LDO. To configure
these options, set JU1 as desired (see Table 1).
