The MAX5386M evaluation kit (EV kit) is an assembled
and tested PCB that features the MAX5386M 50kI dual
digital potentiometers. The MAX5386M IC features dual
volatile 50kI 256-tap, potentiometers and communi-
cates through an SPIK-compatible serial interface.
The MAX5386MEVMINIQU+ 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 3-wire serial inter-
face. Windows

interface for exercising the MAX5386M’s features. The
program is menu driven and offers a graphical user
interface (GUI) complete with buttons, track bars, and
edit boxes. The MAX5386M EV kit software can also be
used to evaluate the MAX5386L, MAX5386N, MAX5388,
MAX5391, and MAX5393. The EV kit can also be inter-
faced directly to a user-supplied 3-wire system.
The MAX5386M 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 a user-supplied
external 2.6V to 5.25V DC power supply. Order the
MAX5386MEVMINIQU+ for a complete PC-based evalu-
ation of the MAX5386M.
The EV kit also contains PCB footprints for the MAX5388,
MAX5391, and MAX5393. To evaluate these parts, order
samples and fit the parts in places U4, U2, and U3,
respectively.
