Evaluation Kit for the MAX9918

Please check latest availability status for a specific part variant.


The MAX9918 evaluation kit (EV kit) provides a proven design to evaluate the MAX9918 wide input range, precision unidirectional/bidirectional, current-sense amplifier in an 8-pin SO package. The EV kit features Kelvin connections for force and sense at the amplifier inputs and a very precise current-sense resistor with a tolerance of ±0.5%. Various test points are included for additional evaluation.

The MAX9918 EV kit PCB comes with a MAX9918ASA+ installed. Contact the factory for free samples of the pin-compatible MAX9919FASA+, MAX9919NASA+, and MAX9920ASA+ to evaluate these devices.
