Evaluation Board

MAX5392EVMINIQU

$83.48

Description/Applications

The MAX5392 evaluation kit (EV kit) is an assembled and tested PCB that features two MAX5392M 50kΩ dual digital potentiometer ICs. The MAX5392M IC features dual volatile 50kΩ 256-tap potentiometers and communicates through an I²C-compatible serial interface (or through a stand-alone 2-wire serial interface).

The MAX5392EVMINIQU+ evaluation system (EV system) includes the EV kit and a MINIQUSB+ interface board. The MINIQUSB+ interface board can be used to enable PC communication through the 2-wire serial interface. Windows® 2000- , Windows XP®-, and Windows Vista®-compatible software provides a professional user interface for exercising the MAX5392 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 also be used to evaluate the MAX5387. The EV kit can also be interfaced directly to a user-supplied 2-wire system.

The MAX5392 IC 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 from a user-supplied external 1.7V to 5.25V DC power supply. Order the EV system (MAX5392EVMINIQU+) for a complete PC-based evaluation of the MAX5392.

The EV kit can also be used to evaluate the MAX5392L (10kΩ) and MAX5392N (100kΩ). The EV kit contains PCB footprints for two MAX5387 ICs, which allows the user to independently control up to eight potentiometers. To evaluate the MAX5387, order samples and install the ICs on U1 and/or U2 PCB pads.

Description

The MAX5387 dual, 256-tap, volatile, low-voltage linear taper digital potentiometer offers three end-to-end resistance values of 10kΩ, 50kΩ, and 100kΩ. Operating from a single +2.6V to +5.5V power supply, the device provides a low 35ppm/°C end-to-end temperature coefficient. The device features an I²C interface.

The small package size, low supply operating voltage, low supply current, and automotive temperature range of the MAX5387 make the device uniquely suitable for the portable consumer market and battery-backup industrial applications.

The MAX5387 is specified over the automotive -40°C to +125°C temperature range and is available in a 14-pin TSSOP package.
