MAX5391L/MAX5391N Evaluation Systems

General Description

The MAX5391L and MAX5391N evaluation kits (EV kits)

are fully assembled and tested PCBs that feature the

MAX5391L (10kI) and MAX5391N (100kI) dual digital

potentiometers, respectively. The MAX5391L/MAX5391N

dual volatile potentiometers communicate through an

SPIK-compatible 3-wire serial interface.

The MAX5391LEVMINIQU+ and MAX5391NEVMINIQU+

evaluation systems (EV systems) include the MAX5391L

EV kit and MAX5391N EV kit, respectively, and a

MINIQUSB+ interface board. The MINIQUSB+ interface

board can be used to enable PC communication through

professional user interface for exercising the MAX5391L/

MAX5391N 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 MAX5386M, MAX5393, and

MAX5388. The EV kits can also be interfaced directly to

a user-supplied 3-wire system.

The MAX5391L/MAX5391N ICs can be powered from

a 1.7V, 2.6V, 3.3V, or 5V source generated from the

MINIQUSB+ interface board and EV kit circuitry, or a user-

supplied external 1.7V to 5.25V DC power supply. Order

the MAX5391LEVMINIQU+ or MAX5391NEVMINIQU+

EV system for a PC-based evaluation of the MAX5391L

or MAX5391N, respectively.

The EV kits also contain PCB footprints for the MAX5386M,

MAX5388, and MAX5393. To evaluate these parts,

order samples and install the ICs on U1, U4, and U3,

respectively.
