Product Details

The MAX44284 evaluation kit (EV kit) provides a proven design to evaluate the MAX44284 high-precision, low-power, current-sense amplifier. This EV kit demonstrates the MAX44284 in an ultra-small, 1.3mm x 0.9mm, 6-bump WLP package.

The EV kit PCB comes with a MAX44284HAWT+ installed, which is the 100V/V gain version. Other gain options are available. Contact the factory for the pin-compatible MAX44284FAWT+ (G = 50V/V), MAX44284WAWT+ (200V/V), and MAX44284EAWT+ (G = 500V/V).

Applications
