Description
The MAX5389 evaluation kit (EV kit) is an assembled and tested PCB that features the MAX5389M 50kΩ dual digital potentiometer. The EV kit provides a mechanical pushbutton-controlled interface or a user-supplied digital interface for the IC digital inputs for changing the potentiometer wipers.
The EV kit operates from an external 2.8V to 5.5V power supply applied at the VIN and GND PCB pads. The MAX5389 operates from a 2.6V to 5.5V VDD supply. Additional LDO regulators are provided to operate the MAX5389 VDD input at 2.6V or 3.3V. The on-board regulators require a 200mV overhead above their respective outputs.
