MAX98357 I2S 3W Class D Amplifier

Description:

The 3W I2S Amplifier Module - MAX98357A is a compact and powerful device that integrates a high-quality audio amplifier and a digital-to-analog converter (DAC) into a single board.

The module connects to a microcontroller or other devices through the I2S (Inter-IC Sound) interface, which allows for digital transfer of audio data. This simplifies the integration and control of the amplifier in a larger system.

With a 3W output power, the 3W I2S Amplifier Module - MAX98357A is ideal for applications with moderate audio power requirements, such as portable speakers, media player projects, or other audio playback devices. The amplifier provides faithful sound reproduction, with low distortion and a good signal-to-noise ratio.

The module also includes options for volume control and tone adjustment, allowing for customization of the audio characteristics according to the user's preferences. It can be powered with a supply voltage ranging from 2.5V to 5.5V, making it versatile and compatible with a wide range of applications.
