• Manufacturer Part Number: MAX5388EVMINIQU+
• Description: Digital Potentiometer Development Tools MAX5386/88/91/93 Eval Kit
• Manufacturer: Maxim Integrated
• Series: MAX5386, MAX5388r

Specifications of MAX5388EVMINIQU+

• Rohs: yes
• Product: Evaluation Systems
• Tool Is For Evaluation Of: MAX5388
• Resistance: 100 kOhms
• Operating Supply Voltage: 2.6 V to 5.25 V
• Interface Type: 3 Wire, Serial, USB

open ended or with ground reference, respectively. Use
jumpers JU17 and JU18 for potentiometer B configura-
tions. Table 6 lists jumper options for configuring poten-
tiometer B.
Potentiometer B can also be configured as a variable
resistor by shorting the HB and WB pads using a wire.
When operating as a variable resistor, any power source
connected to the HB, WB, or LB pads must be voltage
and current limited to the maximum conditions stated in
the MAX5386/MAX5388 IC data sheet.
Note: To test the device in resistor mode, the ohmmeter
must be GND referenced to the MAX5388. This can be
accomplished by connecting the L_ pin to GND or the H_
pin to 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
(U1, U2, and U3) and various jumpers to evaluate the
MAX5386, MAX5391, and MAX5393, respectively.
Jumper JU1 and LDO U5 are available to use as a
1.7V power source when evaluating the MAX5391 and
MAX5393 EV kits. Refer to the MAX5386M, MAX5391L,
MAX5391N, or MAX5393 evaluation system data sheets
for additional information when evaluating the MAX5386,
MAX5391, or MAX5393 digital potentiometers.
