- 1. MAX98357 I2S Class D Amplifier takes standard I2S digital audio input, not only decodes it into analog, but also amplifies it directly into a speaker. Perfect for adding compact amplified sound, it takes 2 breakouts (I2S DAC + Amp) and combines them into one.
- 2. I2S in a digital sound protocol that is used on circuit boards to pass audio data around. Many high end chips and processors manage all of the audio in digital I2S format. To input or output data, three or four pins are used (data in, data out, bit clock and left-right channel select). Usually, for audio devices, there's a DAC chip that will take I2S in and convert it to analog that can drive a headphone.
- 3. Inside the miniature chip is a class D controller, able to run from 2.7V-5.5VDC. Perfect for portable and battery-powered projects. It has built in thermal and over-current protection.
- 4. The audio input is I2S standard, you can use 3.3V or 5V logic data. The outputs are "Bridge Tied" - that means they connect directly to the outputs, no connection to ground. The output is a ~300KHz square wave PWM that is then 'averaged out' by the speaker coil - the high frequencies are not heard. All the above means that you can't connect the output into another amplifier, it should drive the speakers directly.
- 5. There's a Gain pin that can be manipulated to change the gain. By default, the amp will give you 9dB of gain. By connecting a pullup or pull down resistor, or wiring directly, the Gain pin can be set up to give 3dB, 6dB, 9dB, 12dB or 15dB.
- MAX98357 I2S Audio Amplifier Module:The MAX98357 digital input Class D audio power amplifier enables designers to implement a compact, efficient plug-and-play solution at a cost effective price.
- Power Supply:2.5V-5.5V

- Suitable for Raspberry Pi, Arduino, ESP32 and other I2S audio output microcontrollers or development board systems
- 1: Output power: 3.2W at 4Ω, THD is 10%; 8Ω is 1.8W, THD is 10%
- 2: 12S sampling rate: 8Khz~96Khz
- 3: Class D amplifier with optional gain: 3dB/6dB/9dB/12dB/15dB
- 4: No master clock (MCLK) required
- 5: Plug and Play: 35 different clocks and 128 digital audio formats can be automatically configured with only a single power supply
- 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
- MAX98357 I2S 3W Audio Amplifier Board
