Detailed Description of
Evaluation Software
The MAX98390 evaluation software is designed to be
used only with the MAX98390C/D EV system. The soft-
ware provides an intuitive GUI for programming the device
and includes many features intended to aid in evaluation.
There are two methods to reestablish a connection with
the hardware. The first is by selecting Device | Connect
from the menu bar. This instructs the program to con-
nect to the EV system. The second method is to click the
Connect button until it displays Disconnect, which signi-
fies that the EV system is fully connected.
The MAX98390 evaluation software main window
(Figure 1) is composed of four main sections: menu bar,
communication tool bar, tabbed pages, and a status bar.
The menu bar provides additional features to aid evalua-

and Flag_ interrupt registers (0x2002–0x200A). When the
image is red, it indicates that the associated interrupt bit
has been set.
Communication Tool Bar
The tool bar consists of seven buttons, a drop-down
combo box, and a display box. These controls are always
accessible, regardless of the active tabbed page. The
tool bar is shown in Figure 4 and Table 1 provides details
about each control.
The panel also includes checkboxes for each interrupt
that are used to enable the link between an interrupt’s
Flag bit and State bit. When enabled, the Flag bit is set
whenever the State bit is set. To clear the State and Flag
bits, click on the interrupt’s associated Clear button.
Status Bar
The Status bar is divided into four sections. From left to
right: status and alert messages, device part number and
revision ID, interface name and firmware version, and
evaluation system connection status.
Note:
● Each interrupt source must be enabled for the FLAG
column (i.e., flag bits) to be set.
● The IRQ_EN bit needs to be set for the interrupt to
be output on the IRQ pin.
Interrupt Status Panel
The Interrupt Status panel (not to be confused with the
Status bar) displays the state of the Raw, State, and
Flag interrupts. This data is read from the Raw_, State_,

The color of a diagram block changes depending on the
enabled state of the device function(s) associated with
that block. An inactive block is grey, a disabled block is
white, and an enabled block is teal. Figure 5 shows the
block diagram with the device configured for digital audio
interface (DAI) (USB audio) input and speaker output.
Block Diagram Tab
The evaluation software uses an interactive block dia-
gram to facilitate the programming of the device. The
block diagram also provides a visual representation of the
device’s functions and current configuration.
There are three types of blocks in the block diagram,
and they are identified by the cursor image. The cursor
changes to a pointing hand when over a block that opens
a dialog window and a full hand to toggle a function. If
the cursor does not change when over a block, then it
is an inactive block, and is only provided for illustrational
purposes.
Dialog Windows
Dialog windows are associated with specific blocks in the
block diagram and contain the controls for configuring
the registers associated with that functional block. Open
a dialog window by clicking on a dialog block. Figure 7
shows the typical GUI controls that are found on a dialog
window.

device register once the Enter key is pressed. The state
of the bit labels are then updated to reflect the value
shown in the edit box.
Control Registers Tab
The Control Registers tab provides two methods for
configuring the device. As an example, Figure 6 shows
the elements of the interrupt registers.
Note: Trying to write to a read-only bit by clicking/toggling
its label or entering a hex value in its edit box updates the
GUI, but it does not affect the bit’s value in the device. All
read-only bits are updated to reflect their current value in
the device by performing a read all operation.
The first configuration method involves clicking on the
register’s bit labels. A non-bold bit label indicates that the
bit is currently set low. A bold bit label indicates that the bit
is currently set high. Clicking on a bit toggles its state and
results in a write to that register. This action also updates
the value displayed in the register’s edit box, located to
the right of the bit labels.
All changes made on this tab are reflected on the Block
Diagram tab and on any open dialog windows.
The second configuration method involves entering a
hex value in the register’s edit box and then pressing

The save and load features are functional even when the
hardware is not connected. This allows configuration files
to be created and opened when hardware is not available.
Since the configuration file is automatically generated by
the software, it is not meant to be manually formatted and
doing so may cause file loading issues. To open a configu-
ration file for viewing purposes only, use a plain text editor.

Table 2 describes all menu bar items with additional infor-
mation for some menu items provided in the following
sections.
File I/O
The software’s save and load features are accessed from
the File menu. The Save Control Register Settings
feature saves the data currently displayed on the Control
Registers tab.
Select File > Save Control Register Settings to create
a configuration file. The register address and its data are
saved as tab-delimited values and the file is saved with a
.98390 extension.
A configuration file’s main purpose is to capture the current
state of the device’s registers, as displayed on the register
tab. This feature makes it easy to program a device to a
saved/known state and allows for the sharing of configura-
tion files between users. To facilitate usage, use descriptive
file names when saving a configuration file.
The software has a couple standard configuration files
pre-installed. A file can be loaded by selecting File >
Load Register Settings > Pre-Installed Configuration
Files, and using the drop-down menu, select the file, then
clicking Load.

respective supply test-points and/or binding posts. When
using the AUDINT3 board, connect the included 5V power
supply to VBAT (J10). The AUDINT3’s on-board LDO
regulator powers DVDD on the DEV board. This power is
routed to the DEV board through the J1 connector. See
the Digital Audio Interface section.
Detailed Description of Hardware
The MAX98390C/D EV system is designed to allow for
a thorough evaluation of the MAX98390C/D boosted
Class D audio amplifier IC with integrated Dynamic
Speaker Management. The EV system includes either the
MAX98390C or the MAX98390D development board (DEV
board), Maxim’s Audio Interface Board III (AUDINT3), 5V
power supply, and a microspeaker.
Jumper Selection
The DEV board includes jumper JU1 to facilitate a device
reset. Table 4 describes the JU1 configuration options.
Note: Before starting evaluation, ensure that the jumper
is configured as needed.
The DEV board can be evaluated as
a
standalone board that is driven directly by audio test
equipment, powered by multiple external supplies,
2
and configured by an external I C capable controller.
Digital Audio Interface
To simplify the evaluation, the DEV board can be evalu-
ated with the AUDINT3 board and the included 5V power
supply. This hardware combination provides an easy-to-
use method for exercising the capabilities of the device
with no additional audio equipment.
The device DAI is routed to interface header J2 as
well as the AUDINT3 connector J1. The interface
headers provide easy access to the device’s PCM
bus and the AUDINT3 connector allows for USB
audio to be streamed onto the DEV board. See the
USB Audio Input section for details on USB audio stream-
ing and Table 6 for the connector J1 pinout.
The AUDINT3 board provides an on-board LDO regulator,
2
USB-to-PCM, and USB-to-I C interfaces. The AUDINT3
LDO regulator is used to power the device’s DVDD
supply rail through connector J1. The USB-to-PCM
converter accepts a USB audio stream from a USB
DAI Header
The DAI header (J2) provides access to the MAX98390C/D
master clock (MCLK) input, as well as its PCM bus (BCLK,
LRCLK, DIN, and DOUT). This DAI header facilitates
evaluation with audio equipment I/O. See Table 5 for the
pinout of the DAI headers and Figure 8 for an illustration
of how the MAX98390C/D DAI interface is routed through
the DAI headers to the AUDINT3 connector.

connected computer and converts that into an I S data
stream, allowing for USB audio playback through the
2
MAX98390C/D device. The USB-to-I C interface is the
bridge that allows the evaluation software to configure,
2
monitor, and control the I C capable devices on the DEV
and AUDINT3 boards.
Ambient Temperature Sensor
A temperature sensor, DS7505, is included on the
DEV Board. The sensor is connected to the I C bus,

PCM interface, and the USB-to-I C interface allows for
EMI Filter
the use of the MAX98390 evaluation software, making
device configuration and monitoring simpler.
WhenlongspeakercablesareusedwiththeMAX98390C/D
output, a ferrite bead plus capacitor filter can be installed
to prevent excessive EMI radiation. Although it is best to
choose filter components based on EMI test results, the
combination of 680pF capacitors (C11, C12) and Murata
BLM18SG331TN1 ferrite beads (FB1, FB2) generally
work well. Before adding the filters to the design, first
remove the small PCB traces shorting FB1 and FB2 (see
the MAX98390C EV Kit Schematic and the MAX98390C
EV Kit PCB Layout Diagrams).
The DEV board connects to the AUDINT3 board through
connector J1. The physical connections made between
the DEV board and AUDINT3 board are listed in Table 6.
USB Audio Input
To utilize the USB streaming feature of the AUDINT3
board, connect the USB cable from the computer to the
micro USB connector J2 on the AUDINT3 board and
ensure that the AUDINT3 board is connected to the DEV
board.
2
I C Interface
Once the hardware is ready, use the MAX98390 evalua-
tion software to configure and enable the device for DAI
audio playback.
2
The MAX98390C/D’s I C interface is routed to header J2
and connector J1. The J1 connector is for the AUDINT3
board and connects the device’s I C interface to the I C
interface of the AUDINT3 board. This connection allows
the MAX98390 evaluation software to read and write to
the device. See Table 8.

figured to one of eight values: 0x70 (default), 0x72,
0x74, 0x76, 0x78, 0x7A, 0x7C, or 0x7E. The device
address is set by connecting the device’s ADDR1 pin
to GND, SDA, SCL, or DVDD and ADDR2 pin to DVDD
or GND. This is accomplished by installing 0Ω resis-
tors in one of the R13-R16 locations for ADDR1 and
one of the R20-R21 locations for ADDR2. For proper
address programming, only one resistor is used for each
ADDR pin. R13–R16 and R20–R21 are located on the
bottom side of the board and are identified with silk

Audio Interface Board III
Maxim’s Audio Interface Board III (AUDINT3 board) facili-
tates the evaluation of the DEV board by providing a set
of features that can be used to exercise the capabilities
of the DEV board without the need for additional audio

Stereo Testing
Stereo Configuration
1) Insert both 5V power supplies into wall receptacles.
For stereo evaluations, a stereo auxiliary kit is available
that includes a modified DEV board (stereo companion
board), microspeaker, power supply, and 20-pin ribbon
cable. See the Ordering Information section.
2) With the audio source disabled, connect the USB
cable from the computer to the USB port (J2) on the
AUDINT3 board.
The Stereo Companion Board differs from the DEV board
in the following ways:
3) The multicolor LED D1 on the AUDINT3 blinks white.
When the computer registers the AUDINT3 as a USB
device D1 changes to magenta and blinks slowly.
2
● I C address is set to 0x72.
4) Launch DSM Sound Studio and follow the prompts.
● Ambient temperature sensor is not installed.
● J1 is not installed.
5) For further refinement of the hardware configura-
tion, launch the MAX98390 evaluation software. To
select a device to configure, use the Active Device
pulldown menu located in the top banner of the GUI.
Once a device is selected, click the Read All button
to refresh the settings of the GUI.
Stereo Boards Setup
1) Configure the Stereo Companion board the same as
the DEV board. See the DEV Board Setup section.
2) Insert the keyed 20-pin ribbon cable into the J2 con-
nector on the Stereo Companion board, then connect
the other end of the ribbon cable to the J2 connector
on the fully configured DEV board. The ribbon cable
bridges the DVDD power to the Stereo Compan-
