Chip Description
The EG8371 is a power amplifier with selectable AB/D class and no FM interference. With a 5V operating voltage, the maximum drive power is 5W (2Ω, BTL load, THD <10%), and the total harmonic distortion noise is less than 1% within the audio range. The EG8371 uses SOP and ESOP packaging, making it especially suitable for small-volume, lightweight portable systems. Power consumption can be reduced by controlling entry into sleep mode. It has a built-in overheat automatic shutdown protection mechanism; it operates stably, with a gain-bandwidth product as high as 3.1MHz, and is stable at unit gain. Integrated internal feedback allows adjustment of the amplifier's voltage gain and optimal sound quality by configuring external parameters, making it easy to use. It is a perfect solution for your amplifier and USB subwoofer.
