MAX98357 Development Board/

Evaluation System (WLP)

General Description

The MAX98357 development board (DEV board) is a fully

Features

● 2.5V to 5.5V Single-Supply Operation

assembled and tested PCB that evaluates the MAX98357

I S digital input Class D power amplifier. The DEV board

● Only a Single External Component (VDD Capacitor)

Required in Many Applications

operates from a single 2.5V to 5.5V DC power supply and

is capable of delivering 3.2W into a 4Ω load. The device

outputs can be connected directly to a speaker load for

filterless applications. However, a filter can be added to

● I S, Left-Justified, or TDM Input

● Five Selectable Gains (3db, 6dB, 9dB, 12dB, and

15dB)

ease evaluation. The MAX98357A accepts standard I S

● Audio Channel Select (Left, Right, and Mono Mix)

● Filterless Operation

data and the MAX98357B accepts left-justified digital

audio data. Both versions also support 8-channel TDM

audio data.

● Optional Class D Output Filters for Ease of

Evaluation

The MAX98357 evaluation system (EV system) includes

the MAX98357 DEV board and Maxim Integrated’s audio

interface board (MAXAUDINT001# board).

● Proven PCB Layout

● Fully Assembled and Tested

The MAXAUDINT001# board provides an easy-to-use

USB audio-to-I S converter. This allows for any computer

to become a digital audio source, which can be used to

evaluate the devices. The MAXAUDINT001# board can

also be used to power the MAX98357. This allows for a

complete evaluation from a single USB connection.
