MAX5387 Evaluation System
and JU4 for U1 potentiometer A and jumpers JU5 and
JU6 for U1 potentiometer B configurations. Tables 6
and 7 list the jumper options for configuring U1 poten-
tiometers A and B. Use jumpers JU18 and JU19 for U2
potentiometer A and jumpers JU20 and JU21 for U2
potentiometer B configurations. Tables 8 and 9 list the
jumper options for configuring U2 potentiometers A and
B.
The MAX5387 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_ pad must be
voltage and current limited to the maximum conditions
stated in the MAX5387 IC data sheet.

Note: To test the device in resistor mode, the ohmmeter
must be GND referenced to the MAX5387. This can be
accomplished by connecting the L_ pin to GND or the H_
pin to the MAX5387’s VDD input. Resistance can then be
measured between W_ and L_ or W_ and H_ PCB pads.
The EV kit can also evaluate the MAX5387M and
MAX5387N. Remove either U1 and/or U2 and replace
them with the desired IC.
The EV kit is populated with additional PCB footprints
(U3, U4) and various jumpers to evaluate two MAX5392
ICs. See Table 10 for proper jumper configurations when
evaluating the MAX5392 IC. Also refer to the MAX5392
EV system data sheet for additional information.
