DESCRIPTION

The I2S MAX98357 is a Class D audio amplifier that offers high-quality audio amplification and is specifically designed for digital audio applications.

Suitable for microcontrollers or development board systems with I2S audio output such as Raspberry Pi, Arduino, and ESP32.


FEATURES

  • Class D Amplification: The MAX98357 is a Class D amplifier, known for its efficiency and low heat generation. It is capable of delivering high-quality audio with minimal power loss, making it suitable for portable and battery-powered devices.
  • I2S Digital Audio Interface: The amplifier is equipped with an I2S (Inter-IC Sound) digital audio interface, which allows for direct connection to digital audio sources, such as microcontrollers, DSPs, and audio codecs. This digital interface ensures high fidelity and minimal signal degradation.
  • High Efficiency: In addition to its small form factor, class D amplifiers like the MAX98357 are highly efficient, resulting in less power consumption and longer battery life for portable devices. The Class D design switches the output transistors rapidly, minimizing heat dissipation. The device is capable of achieving a 3.2W Class AB amplifier with Class D amplifier efficiency, resulting in excellent high-fidelity sound for a variety of product applications.
  • Wide Voltage Range: The MAX98357 operates over a wide voltage range, typically from 2.7V to 5.5V, which makes it compatible with a variety of power sources and battery configurations.
  • Low Total Harmonic Distortion (THD): This amplifier is designed to maintain low THD, ensuring that the amplified audio output remains faithful to the original source signal, with minimal distortion.
  • Integrated Digital Volume Control: The MAX98357 often includes an integrated digital volume control, allowing for precise adjustment of the audio output level. This feature eliminates the need for external potentiometers or analog volume control components.
  • Short-Circuit and Over-Temperature Protection: The amplifier typically includes built-in protection mechanisms to safeguard against short-circuits and over-temperature conditions, enhancing the overall reliability of the audio system.
  • Selectable Gain: Many versions of the MAX98357 allow users to select different gain settings to adapt the amplifier's output to specific audio requirements and speaker sensitivities.
  • Audio Performance: This amplifier provides high signal-to-noise ratios (SNR) and dynamic range, ensuring clean and clear audio output.
