MAX98357EVSYS#WLP: 3.2W x2 @ 4Ω, 2.5 ~ 5.5V in, Class D

Summary

The MAX98357 development board (DEV board) is a fully assembled and tested PCB that evaluates the MAX98357 I2S digital input Class D power amplifier. The DEV board operates from a single 2.5V to 5.5V DC power supply and is capable of delivering 3.2W into a 4Ω load. The deviceoutputs can be connected directly to a speaker load for filter-less applications. However, a filter can be added to ease evaluation. The MAX98357A accepts standard I2S data and the MAX98357B accepts left-justified digital audio data.

Both versions also support 8-channel TDM audio data. The MAX98357 evaluation system (EV system) includes the MAX98357 DEV board and Maxim Integrated’s audio interface board (AUDINT001 board).

The AUDINT001 board provides an easy-to-use USB audio-to-I2S converter. This allows for any computer to become a digital audio source, which can be used to evaluate the devices. The AUDINT001 board can also be used to power the MAX98357. This allows for a complete evaluation from a single USB connection.
