The MAX5387 evaluation kit (EV kit) is an assembled
and tested PCB that features the MAX5387L 10kI dual
digital potentiometer. The MAX5387 EV kit is populated
with two MAX5387L ICs and communicates through an
I
2-wire serial interface).
The MAX5387EVMINIQU+ evaluation system (EV sys-
tem) includes the EV kit and the MINIQUSB+ interface
board. The MINIQUSB+ interface board can be used to
enable PC communication through the 2-wire serial inter-
face. Windows
Vista
interface for exercising the MAX5387’s features. The pro-
gram is menu-driven and offers a graphical user inter-
face (GUI) complete with buttons, track bars, and edit
boxes. The EV kit software can also be used to evaluate
the MAX5392. The EV kit can also be interfaced directly
to a user-supplied 2-wire system.
The MAX5387 IC can be powered from a 2.6V, 3.3V,
or 5V source generated from the MINIQUSB+ inter-
face board and EV kit circuitry, or from a user-supplied
external 2.6V to 5.25V DC power supply. Order the
MAX5387EVMINIQU+ for a complete PC-based evalua-
tion of the MAX5387.
The EV kit can also be used to evaluate the MAX5387M
and MAX5387N. The EV kit contains PCB footprints for
two MAX5392 ICs, which allows the user to indepen-
dently control up to eight potentiometers. To evaluate
the MAX5392, order samples and fit the parts in places
U3 and U4.
