MAX98357: Plug-and-Play I2S Class D Amplifier
The MAX98357 is a high-efficiency, digital input Class D audio amplifier that provides a simple and cost-effective way to add sound to your projects. It takes a digital I2S audio signal and converts it directly to an analog output for a speaker, delivering up to 3.2W of power. By skipping the internal DAC and analog stage of the microcontroller, it ensures crystal-clear audio without the background hiss typical of analog amplifiers.
- Digital Simplicity: No need for a separate DAC or analog wiring—just pure digital I2S.
- Powerful Output: Drives 4Ω or 8Ω speakers with ease.
- Automatic Configuration: Automatically detects 35 different sampling rates and digital audio formats.
- Thermal and Short-Circuit Protection: Built-in safety for reliable operation.
