1-5PCS Max98357 Amplifier Module Filterless Audio Board For Raspberry Pi ESP32

Popular

    Product Introduction

    Features
    1. Made of high quality materials, durable and practical
    2. In order to achieve excellent sound quality, the device adopts a high noise immunity digital input with high jitter tolerance (at least 8dB better than common solutions)
    3. Stable performance, capable of achieving 3.2W class-AB amplifier sound quality at class-D amplifier efficiency.
    4. The product also provides excellent electromagnetic interference (EMI) suppression, allowing the use of long lines to connect speakers, without the need to add external filtering
    5. Excellent high-fidelity sound, suitable for a variety of product applications
     
    Specification
    01 Output power:
    3.2W at 4Ω, THD 10%.
    1.8W at 8Ω, THD is 10%.
    I2S sampling rate: 8Khz~96Khz
    Class D amplifier gain selectable: 3dB/6dB/9dB/12dB/15dB
    No need for master clock (MCLK)
