The MAX9938 evaluation kit (EV kit) provides a proven design to evaluate the MAX9938 high-side current-sense amplifier, which offers precision accuracy specifications of VOS less than 500µV (max) and gain error less than 0.5% (max). This EV kit demonstrates the MAX9938 in a tiny 1mm x 1mm x 0.6mm, 4-bump UCSP™ package. The MAX9938 is also available in a 5-pin SOT23, but that package is not compatible with this EV kit.
The MAX9938 EV kit PCB comes with a MAX9938FEBS+ installed, which is the 50V/V gain version. Contact the factory for free samples of the pin-compatible MAX9938TEBS+ and MAX9938HEBS+, which are 25V/V and 100V/V gain versions, respectively.
