Five-module I2S amplifier kit

This pack contains three MAX98357 I2S audio amplifier modules ready for soldering. Each module accepts a single 2.5 V to 5.5 V supply and requires no master clock. The filterless Class D design suits microcontroller projects that expose an I2S audio stream such as Arduino, ESP32 or Raspberry Pi boards.

Thermals noise and power

Class D topology keeps heat low during normal playback at the rated 3.2 W into 4 Ω or 1.8 W into 8 Ω at 10 % THD. The digital input provides high noise immunity and jitter tolerance, while built-in electromagnetic-interference suppression allows long speaker leads without extra filtering. Selectable gain steps of 3 dB, 6 dB, 9 dB, 12 dB or 15 dB let you match output level to the speaker.

Build integration

Pin headers expose LRC, BCLK, DIN, GAIN, SD, GND and VCC for direct wiring to an I2S-capable host. The modules support sampling rates from 8 kHz to 96 kHz and auto-configure across 35 clock schemes and 128 digital audio formats. Buyers who need more than three channels or a pre-assembled board will need a different solution.

Questions about this item

How do I wire the GAIN pin on the MAX98357 module to select the 12 dB setting?

Connect the GAIN pin directly to VCC to set the amplifier gain to 12 dB.

What maintenance or replacement will the MAX98357 amplifier modules need over time?

The modules are solid-state with no moving parts; no scheduled maintenance is required, and they only need replacement if physically damaged.

At what output power does the MAX98357 hit its 10 % THD limit on a 4 Ω load?

The 10 % total harmonic distortion limit is reached at 3.2 W into 4 Ω.
