    Product Details

    The MAX9634 evaluation kit (EV kit) provides a proven design to evaluate the MAX9634 high-side current-sense amplifier, which offers precision accuracy specifications of VOS less than 250µV (max) and gain error less than 0.5% (max). This EV kit demonstrates the MAX9634 in a tiny 1mm x 1mm x 0.6mm, 4-bump UCSP™ package. The MAX9634 is also available in a 5-pin SOT23, but that package is not compatible with this EV kit.

    The EV kit PCB comes with a MAX9634FERS+ installed, which is the 50V/V gain version. Contact the factory for free samples of the pin-compatible MAX9634TERS+, MAX9634HERS+, and MAX9634WERS+, which are 25V/V, 100V/V, and 200V/V gain versions, respectively.
