The MAX5389 evaluation kit (EV kit) is an assem-
bled and tested PCB that features the MAX5389M
50kI 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 regu-
lators require a 200mV overhead above their respective
outputs.
Note: Indicate that you are using the MAX5389 when contacting these component suppliers.
