to their midscale positions. The lower Potentiometer A

and Potentiometer B group boxes provide controls to

change the respective wiper positions. The main win-

dow’s bottom-left status bar provides the USB interface

circuit communication status.

Graphical User Interface (GUI) Panel

The MAX5388 EV kit software GUI shown in Figure 1 is

a Windows program that provides a convenient means

to control the MAX5388 dual potentiometer. Use the

mouse or press the Tab key to navigate through the GUI

controls. The correct SPI write operations are generated

to update the MAX5388 internal memory registers when

any of these controls are executed.

The EV kit software can also be used to evaluate

the MAX5386, MAX5388L, MAX5388M, MAX5391, and

MAX5393.

Software Startup

Upon startup, the EV kit software automatically searches

for the USB interface board’s circuit connection. In the

Interface group box, the Device Connected combo box

allows the user to select the proper part being evalu-

ated. Upon selection of the device being evaluated, the

Update Pot A and B checkbox is enabled/disabled. The

EV kit enters the normal operating mode when the USB

The software divides the EV kit functions into group

boxes. The Interface group box indicates the EV kit

Status and the last write operation Command Sent

and Data Sent indicators. This data confirms proper

device operation. The Device Connected combo box

selects the Maxim part being evaluated and enables

the Update Pot A and B checkbox function when

choosing the MAX5391 or MAX5393 option from the

Figure 1. MAX5388 Evaluation Kit Software Main Window

and the wiper position is updated with the data sent.

The wiper position is shown in the HW_ and WL_ edit

boxes. The HW_ edit box shows the wiper position with

respect to the potentiometer H_ end point and the WL_

edit box shows the wiper position with respect to the

potentiometer L_ end point.

Since the MAX5388 does not have read capability, all

the edit boxes are set to question marks (??) and the

Potentiometer_ track bar is set to midscale. If the USB

connection is not detected, the software prompts the

user to retry, exit the program, or enter the demo mode.

Demo Mode

The EV kit software enters the demo mode—when the

USB connection is not detected—by selecting Cancel

on the MAX5388 Evaluation Kit Interface Circuit

popup window (Figure 2). The software can also enter

demo mode at any time from the main window by select-

ing the Options | Demo Mode menu item. When in

demo mode, all software communication to the EV kit

circuit is disabled; however, most of the software GUI is

functional. Demo mode allows the user to evaluate the

software without hardware connectivity. To exit demo

mode, deselect the Options | Demo Mode menu item.

Factory Default

Pressing the Default button resets the potentiometer A

and B wiper positions to the factory-default midscale

position.

Status Indicator

The Status indicator in the Interface group box displays

EV Kit Operational when the EV kit enters the normal

operating mode after the USB connection is detected.

If the USB connection is not detected, or when the

software enters the demo mode, the Status indicator

displays Demo Mode. Demo mode is used to exercise

the software without hardware connectivity.

Potentiometer A and B Wiper Positions

The wiper position track bars (WA, WB) in the

Potentiometer A and Potentiometer B group boxes

are used to change the wiper position between the H_

and L_ end points. Use the computer mouse or arrow

keys to move the wiper position between the 256 posi-

tion points. The wiper position can also be changed by

entering the desired integer value in the edit boxes, or

by pressing the up or down arrows in the respective

edit box. A change in the W_ wiper position track bars,

or HW_/WL_ edit boxes, writes to the volatile memory

Command Sent Indicator

The Command Sent indicator in the Interface group

box displays the last command sent from the master

(software) to the MAX5388. There are two commands

available in the MAX5388 IC. Table 2 describes the two

MAX5388 commands.

Data Sent Indicator

The Data Sent indicator in the Interface group box dis-

plays the last data sent from the master (software) to the

MAX5388. The Data Sent indicator displays the last data

the Send & Receive MSB first checkbox and verify that

the CPOL=1(clock idle high) and CPHA=1(sample 2^nd

The MAX5388 IC uses an 8-bit (MSBs, D7–D0) data byte

to set the wiper position. Refer to the MAX5386/MAX5388

IC data sheet for additional information.

The Send and Receive Data group box allows the

user to send data to the MAX5388. The Data bytes to

be written edit box indicates data to be sent from the

master (microcontroller) to the device (MAX5388). Eight-

bit hexadecimal numbers should be comma delimited.

Press the Send Now button to transmit the data from the

master to the device. Data appearing in the Data bytes

received edit box is data read from the device. The Data

bytes received edit box in the EV kit software always

shows a default value of 0xFF since the MAX5388 does

not send data back to the master.

Keyboard Navigation

Press the Tab key to select each GUI control. The select-

ed control is indicated by a dotted outline. Using Shift +

Tab moves the selection to the previously selected con-

trol. Buttons respond to the keyboard’s space bar and

some controls respond to the keyboard’s up and down

arrow keys. Activate the program’s menu bar by press-

ing the F10 key and then press the letter of the desired

menu item. Most menu items have one letter underlined,

indicating their shortcut key.

Note: The SPI dialog boxes accept numeric data in

hexadecimal format. Hexadecimal numbers must be pre-

fixed by $ or 0x. Figure 3 shows a simple SPI write-byte

operation using the included 3-wire interface diagnostics

tool. In this example, the software is sending command

0x01 (write to potentiometer B) and data 0x7F. The data

sequence sets the MAX5388 wiper position to 127.

When a number is entered into the edit boxes, it can be

sent to the device by pressing the Enter key. It is also

sent when Tab or Shift + Tab is pressed.

Simple SPI Commands

There are two methods for communicating with the EV

kit, through the normal user-interface panel (Figure 1) or

through the advanced user interface available by select-

ing the 3-Wire Interface (Figure 3) utility from the main

program’s Options | Advanced User Interface menu

bar. A window is displayed that allows SPI send/receive

data operations.

General Troubleshooting

Problem: Software reports it cannot find the interface

circuit.

•ꢀ Is the USB cable connected to the MINIQUSB+

board?

•ꢀ Has Windows plug-and-play detected the board?

Bring up Control Panel->System->Device Manager,

and look at what device nodes are indicated for USB.

If there is an Unknown device node attached to the

USB, uninstall it—this forces plug-and-play to try

again.

On the 3-wire interface tab, the Connection group box

defines the hardware connections of the interface. For

the EV kit, K10 is selected from the Clock (SCK)(SCLK)

drop-down list, K12 from the Data from master to slave

(MOSI)(DIN) drop-down list is disabled, K11 from the

Data from slave to master (MISO)(DOUT) drop-down

list, K9 from the Chip-select (CS) for data framing

drop-down list, and Use standard connections for

•ꢀ If using an off-board SPI interface, is the power

ground connected to the EV kit ground (GND) at one

of the header J1 pin connections (J1-2, J1-4, J1-6,

or J1-8)?

The Configuration group box allows the user to config-

ure the logic level and data rate. For the EV kit, check

MAX5388 Evaluation System

SPI Clock and Data-/Chip-Select Inputs

Detailed Description of Hardware

The MAX5388 features a clock and data-/chip-select

input pins for SPI-compatible communication to con-

trol the MAX5388 wiper position. The clock, data-, and

chip-select pins can be driven by the MINIQUSB+

interface circuit or the PCB header (J1), along with a

user-supplied external SPI-compatible controller. An

external SPI-compatible controller can be connected to

CS (J1-3), DIN (J1-5), SCLK (J1-7), and GND (J1-2) on

header J1 to communicate with the MAX5388 IC. When

using an external SPI-compatible controller, verify that

the MINIQUSB+ interface board has been disconnected

from the EV kit’s J2 and J3 headers. See Table 4 for

header J1 pin assignment.

The MAX5388 EV kit is an assembled and tested PCB

that features the MAX5388N 100kI dual digital poten-

tiometers. Both potentiometer A and B have an end-

to-end resistance of 100kI and each wiper can be

programmed independently among 256 tap positions.

The MAX5388 IC consists of one digital potentiometer in

a variable-resistor configuration and one digital potenti-

ometer in a voltage-divider configuration The EV kit uses

a MAX5388N IC in a 10 µMAX package on a proven two-

layer PCB design.

The EV kit provides connector J1 to interface with the

MAX5388 CS, DIN, SCLK, and GND signals directly to

a user-supplied 3-wire system. Connector J1 also pro-

vides a connection for the EV kit’s 2.6V to 5.5V VPOWER

power-supply input.

Potentiometer, Variable Resistor with

Ground Reference (Potentiometer A)

The MAX5388 IC potentiometer A is internally configured

as a variable resistor. The EV kit allows potentiometer A

to be configured with ground reference by shorting LA

to ground. Table 5 lists jumper options for configuring

potentiometer A.

The EV kit is typically used with a MINIQUSB+ interface

board for communicating with a PC through the 3-wire

serial interface. Logic-level translators U7 and U8 pro-

vide proper SPI interface translation when using 2.6V to

5.5V to power the MAX5388 VDD input.

Verify that any power source connected to the WA or LA

pads are voltage and current limited to the maximum con-

ditions stated in the MAX5386/MAX5388 IC data sheet.

MAX5388 VDD Input Source

The VPOWER rail is typically supplied as 3.3V or 5V by

the MINIQUSB+ interface board circuitry, or 2.6V using

LDO regulator U6. The VPOWER rail sets the MAX5388

VDD input to 5V, 3.3V, or 2.6V. See Table 3 for proper

jumper configurations for setting the MAX5388 VDD input.

Potentiometer, Voltage-Divider or Variable Resistor,

with Ground Reference (Potentiometer B)

The EV kit provides an option to configure the MAX5388

potentiometer B as a potentiometer or voltage-divider,

The EV kit is populated with additional PCB footprints

(U1, U2, and U3) and various jumpers to evaluate the

MAX5386, MAX5391, and MAX5393, respectively.

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.

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.

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.
