The EV kit provides an option to configure the MAX5386M
as a potentiometer or voltage-divider, open end, or
with ground reference, respectively. Use jumpers
JU3 and JU4 for potentiometer A, and jumpers JU5 and
JU6 for potentiometer B configurations. Tables 7 and 8 list
jumper options for configuring potentiometers A and B.
The MAX5386M IC can also be configured as a variable
resistor by shorting the H_ and W_ pads together using
a wire. When operating as a variable resistor, any power
source connected to the H_, W_, or L_ pads must be
voltage and current limited to the maximum conditions
stated in the MAX5386 IC data sheet.

Note that to test the device in resistor mode, the ohmme-
ter must be GND referenced to the MAX5386M. This can
be accomplished by connecting the L_ pin to GND or
the H_ pin to U1 VDD. Resistance can then be measured
between W_ and L_ or W_ and H_ PCB pads.
The EV kit is populated with additional PCB footprints
and various jumpers to evaluate the MAX5391 (U2),
MAX5393 (U3), and MAX5388 (U4), respectively.
Refer to the MAX5388, MAX5391L, or MAX5393 EV sys-
tem data sheets for additional information when evaluating
the_ MAX5388, MAX5391, or MAX5393 digital potentiom-
eters.
