MAX9918EVKIT+

评估套件, MAX9918, 电流检测放大器, 单/双向, -20V至+ 75V输入

The from Products is a MAX9918 evaluation kit. 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 SOIC 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. The MAX9918 measures the load current and provides an analogue output voltage. The full-scale VSENSE on the MAX9918 is 50mV, allowing for 1A max load with a 50mohm current sense resistor. Higher load currents can be accommodated by adding a current-sense resistor in parallel with R3.
