Product Features

  • The MAX98357 Pulse Code Modulation (PCM) plug-and-play speaker amplifiers take advantage of the flexibility of Maxim's pinout. 35 different clocks and 128 digital audio formats can be automatically configured with a single power supply.
  • This DAC was a cheap and brilliant way to improve the audio quality of your esp32 project. It turned awful sound quality with horrible background noise to incredibly clear and enjoyable sound. you personally found lowering the gain to 3db worked best for your project.
  • CHIP:MAX98357
  • the device uses a high noise immunity digital input with high jitter tolerance. It also provides excellent electromagnetic interference suppression, allowing long-line connected speakers without the need for external filtering.
  • Suitable for microcontrollers or development board systems with I2S audio output such as Compatible with Arduino Raspberry Pi, ESP32
