Analog Devices MAX22420/MAX22421 Evaluation Kit provides a proven design to evaluate the MAX22420/1 and MAX22820/1 ultra-low-power, 2-channel digital isolators. The MAX22420/1 and MAX22820/1 are housed in an 8-pin NSOIC or 8-pin WSOIC package. The MAX2242XSEVKIT# is a generic board with U1 unpopulated, allowing the user to select a device from the MAX22420/MAX22421 family. The MAX22820/MAX22821 is functionally equivalent to the MAX22420/MAX22421 but in an 8-pin WSOIC package. Analog Devices MAX22420/MAX22421 Evaluation Kit should be powered from two independent isolated power supplies with a nominal output range of 1.71V to 5.5V. A single power supply can also be used to evaluate the device’s electrical parameters without any isolation between the two sides.
