XPT4809，5V 105mw 音频功率放大器

Chip Function Description

XPT4809 is a dual channel audio power amplifier. Each channel can provide an average power of 105mW (5V working voltage, 16Q load, THD+N=0.1%), and the total distortion+noise within the audio range is less than 0.1% (20Hz~20KHz):

The application circuit of XPT4809 is simple, requiring only a few peripheral devices:

The XPT4809 output does not require a bootstrap capacitor or buffer network, and is packaged in MSOP and SOP to save circuit area. It is very suitable for low voltage and low power applications such as mobile phones and various mobile devices
