MAX4173 Evaluation Kit
Evluates:MAX4173
General Description
Features
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 proportion-
al to the load current flowing through an external sense
resistor.
o Real-Time Current Monitoring
o Wide 0 to 28V Input Common-Mode Range
Independent of Operating Supply Voltage
o
0ꢀ.5 ꢁull-Sꢂale ꢃꢂꢂuraꢂy
o Lead(Pb)-ꢁree and RoHS Compliant
o ꢁully ꢃssembled and Tested
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-sup-
plied, external sense resistor. The user can easily
match the full-scale sense voltage to the required out-
put-voltage range.
