The MAX4173 evaluation kit (EV kit) is a fully assembled and tested surface-mount PCB that contains a MAX4173TEUT+. The MAX4173 is a high-side, current-sense amplifier with an input common-mode voltage range that extends from 0 to 28V. The current-sense amplifier provides an analog voltage output proportional to the load current flowing through an external sense resistor.
The 20V/V gain version of the MAX4173 (MAX4173TEUT+) and a 150mΩ sense resistor are installed on the board. Other gain versions of the MAX4173 can be evaluated by replacing the MAX4173TEUT+ with a MAX4173FEUT+ (50V/V) or a MAX4173HEUT+ (100V/V) and a user-supplied, external sense resistor. The user can easily match the full-scale sense voltage to the required output-voltage range.
