box disables the zero-crossing detection (ZCD) during a

volume change operation when checked. When enabled

(unchecked), the ZCD forces all volume adjustment to

be made when the output signal is crossing zero, thus

reducing audio clicks during volume changes.

Software Startup

Upon starting the program, the MAX97001 EV kit soft-

ware automatically searches for the USB interface cir-

cuit and then for the MAX97001 device address. The

MAX97001 EV kit enters the normal operating mode

when the USB connection is detected and has found the

device address. If the USB connection is not detected,

the software prompts the user to retry or enter the demo

mode.

Input Gain

The MAX97001 EV kit software’s Input_ Gain group

box selects the input channel preamp gain for the

MAX97001. The MAX97001 input channel preamp gain

is selectable between -6dB, -3dB, 0dB, +3dB, +6dB,

+9dB, and +18dB.

Demo Mode

The MAX97001 EV kit software enters the demo mode

when the USB connection is not detected, or by select-

ing the Options_ |_ Demo_ Mode menu item in the main

window. When in demo mode, all software communica-

tion 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.

If the USB cable is connected to the EV kit, but power

is not applied to PVDD, the EV kit GUI acts like it is in

demo mode. In such a case, the EV kit is connected to

the PC through USB and I²C commands can be sent to

the MAX97001. However, without power, the MAX97001

does not acknowledge the I²C commands. When power

is applied, press the Reset button to detect the pres-

ence of the MAX97001.

Charge Pump

The MAX97001 features an internal charge pump for

Maxim’s Class H DirectDrive architecture. The charge

pump operates in two modes, fixed mode and high-effi-

ciency mode. By default, the MAX97001 charge pump

operates in high-efficiency mode. High-efficiency mode

on the charge pump dynamically changes the internal

supply rails. To have fixed internal supply rails, check the

Fixed_Mode checkbox in the Charge_Pump group box.

Within fixed mode, there are two options for the supply

rails shown in the drop-down list, Q1.8V and Q0.9V.

Distortion Limiter

The distortion limiter limits distortion based on the

defined THD level and has programmable release time.

Write All/Read All/Reset

The Write_All button writes the current settings to all the

registers on the GUI. The EV kit software GUI performs

I²C write commands as changes occur on the GUI. The

Read_ All button changes the GUI settings to match

the MAX97001 register settings. To change settings

one time, enter demo mode by selecting the Options_|_

Demo_Mode menu item, change the GUI to the required

settings, exit demo mode by selecting Options_|_Demo_

Mode, and then press the Write_ All_ button. If further

changes are not required, enter demo mode to dis-

able communication to the MAX97001. To obtain the

MAX97001 settings, exit demo mode and press the

Read_All button. The Reset button clears the EV kit soft-

ware GUI and reprograms the MAX97001 to the default

values.

Switch Enable

The MAX97001 features an internal switch that can

bypass the Class D amplifier and allow an external

amplifier to power the same speaker connected to the

MAX97001 EV kit without requiring external switches.

Connect the external amplifier output to COM1 and

COM2, and enable in the software by checking the

Switch_Closed checkbox in the Analog_Switch group

box.

Low-Power Mode

The MAX97001’s low-power mode minimizes current

consumption when only using the headphone amplifier.

Low-power mode transmits a single-ended audio signal

to the headphone amplifier from either INA or INB, or a

differential signal from INA and INB. Low-power mode

can be enabled by clicking on the LP_Mode drop-down

list. The volume control and mixer are bypassed in this

mode.

MAX97001 Master Controls

The EV kit software’s MAX97001_Master_Controls group

box contains ENABLE, Volume_Slew_Disable, and Zero_

Crossing_Detection_Disable checkboxes. The ENABLE_

checkbox, which is also called the software shutdown,

enables or disables the MAX97001. The Volume_Slew_

Disable checkbox, when checked, disables the volume

slewing. The Zero_Crossing_Detection_Disable check-

Mixer

The speaker, left headphone, and right headphone

each have an independent mixer. The MAX97001 EV kit

accepts a pair of single-ended audio inputs for stereo

er and headphones are defined as IN_1 (left) and IN_2

(right). In the Input_ Configuration group box, select

Stereo_(S/E) for single-ended stereo operation or Mono_

(DIF) for differential mono operation. Depending on the

selection, the speaker and headphone mixers provide

options for selecting the audio source for the SPKR_

HP_Enable checkboxes enable the headphone amplifiers.

The Left_ Headphone_ Volume and Right_ Headphone_

Volume track bars set the left and right headphone

volume, respectively, to between -64dB (min) to +6dB_

(max). Alternatively, the user can enter a numerical

value inside the Left_ Headphone_ Volume and Right_

Headphone_Volume edit boxes.

I²C Interface Indicator

The MAX97001 EV kit software Interface group box dis-

plays the MAX97001’s_ I²C_ Device_ Address, Register_

Address, and the last Data_ Sent. The MAX97001 I²C

device address is internally set to 0x9A.

Speaker Amplifier

The MAX97001 EV kit software’s Speaker_ Amplifier

group box contains the speaker mixer, speaker volume,

and speaker-enable control. Check the Speaker_Enable

checkbox to enable the speaker amplifier. The Speaker_

Volume track bar sets the speaker volume between

-30dB (min) to +20dB (max). Alternatively, the user can

enter a numerical value inside the Speaker_Volume edit box.

Simple I²C Commands

There are three methods for communicating with the

MAX97001 EV kit, through the Main_Control tab (Figure

1), the Registers tab (Figure 2), or by using low-level

SMBusK commands available in the Advanced_ User_

Interface window (Figure 3). Select the Options_|_Interface

(Advanced_ User_ Interface) menu item to display the

Advanced_User_Interface window that allows I²C opera-

tions, such as SMBusReadByte and SMBusWriteByte.

any filtering. Use the OUT+/OUT- test points to connect

the speaker directly to the MAX97001 outputs using a

twisted-pair cable. Do not install inductors L1 and L2 for

maximum efficiency.

Detailed Description of Hardware

The MAX97001 EV kit evaluates the MAX97001 Class D

audio amplifier and stereo DirectDrive headphone ampli-

fier that communicate over I²C. The EV kit demonstrates

the MAX97001 features, such as user-defined input con-

figuration, input gain, input source, output enable, and

volume control.

Filtered Output

Audio analyzers typically cannot accept pulse-width-

modulated (PWM) signals at their inputs. Therefore, the

MAX97001 EV kit includes a pair of lowpass filters at

the output to ease evaluation. To use the filtering output

pads (FOUT+/FOUT-), install inductors L1 and L2 (pro-

vided with the EV kit), connect the load between FOUT+

and FOUT-, and connect the filtered output to the audio

analyzer. The lowpass filters at the speaker outputs are

optimized for an 8I speaker.

The EV kit uses the MAX97001 IC in a 20-bump WLP

(2mm x 2mm) package on a proven four-layer PCB

design. The MAX97001 EV kit operates from a 2.7V to

5.5V supply for PVDD and a 1.8V supply for VDD.

Filterless Output

The MAX97001 EV kit’s filterless outputs (OUT+/OUT-)

can be connected directly to a speaker load without
