MAX98357 I2S 3W Class D Filterless Audio Amplifier Module for Raspberry Pi / ESP32

MAX98357 I2S 3W Class D Filterless Audio Amplifier Module for Raspberry Pi/ESP32

Features:

• The MAX98357 Pulse Code Modulation(PCM)and MAX98358 Pulse Density Modulation(PDM)plug-and-play speaker amplifiers take full advantage of Maxim's flexible bow and pin arrangements

• Output Power: 3.2W at 40, 10%THD, 1.8W at 80, 10%THD

• 12S sampling rate: 8Khz~96Khz

• Class D amplifier Gain selectable: 3dB/6dB/9dB/12dB/15dB

• No master clock(MCLK)required

• Plug and Play:35 different clocks and 128 digital tones can be automatically

• configured with only a single power supply

• Suitable for Raspberry Pi, Arduino and ESP32, and other tools, with 12Saudio output Controller or development board system

• Compared to typical analog amplifier solutions, the component count is greatly reduced, resulting in a significant reduction in solution size

• These features allow users to take advantage of Maxim's cost-effective wafer-level packaging (WLP)without the need for expensive PCB VIAs since most users control the volume digitally

• To achieve excellent sound quality, the device uses digital inputs with high noise immunity and high jitter tolerance(at least 8dB better than competing solutions)

• The device also provides excellent electromagnetic interference (EMI) rejection, allowing long-term speaker connections without the need for additional external filtering

• In addition, the device offers the industry's highest Class D efficiency

Package includes:

• 1 x Module

• 1 x Pin headers(Random Color)
