The MAX5388 evaluation kit (EV kit) is an assembled

and tested PCB that features the MAX5388N 100kΩ dual

digital potentiometers. The MAX5388 IC consists of one

digital potentiometer in a variable-resistor configuration

and one digital potentiometer in a voltage-divider config-

uration and communicates through an SPI™-compatible

serial interface.

The MAX5388EVMINIQU+ 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 MAX5388’s features. The

program is menu driven and offers a graphical user

interface (GUI) complete with buttons, track bars, and

edit boxes. The EV kit software can be used to evaluate

the MAX5386, MAX5388L, MAX5388M, MAX5391, and

MAX5393. The EV kit can also be interfaced directly to a

user-supplied 3-wire system.

The MAX5388 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

MAX5388EVMINIQU+ for a complete PC-based evalua-

tion of the MAX5388.

The EV kit also contains PCB footprints for the MAX5386,

MAX5391, and MAX5393. To evaluate these parts, order

samples and fit the parts in places U1, U2, and U3,

respectively.
