Description

The MAX98357 I2S 3W Class D Amplifier is a digital-to-analog audio amplifier module that takes an I2S digital audio input and outputs an amplified analog signal directly to a speaker, skipping the need for a separate DAC and amplifier chain.

It delivers up to 3.2W into a 4Ω load at 5V with 10% THD, and operates across a 2.5V–5.5V supply range, making it usable with both 3.3V and 5V logic systems. As a Class D amplifier, it reaches efficiency up to 92%, generating less heat than linear amplifier designs.

The module runs filterless, reducing external component count, while offering ultra-low EMI and click-and-pop suppression to avoid audible artifacts on power-up and power-down.

Features:

I2S digital audio input
3.2W output into 4Ω at 5V, 10% THD
Class D efficiency up to 92%
Operating voltage: 2.5V–5.5V DC
Filterless operation, fewer external components
Ultra-low EMI design
Click-and-pop suppression
