XPT9812 is a section 6 w, no FM interference, AB/class D optional type, with 64 series the tone volume, dual channel high power amplifier. 5 v working voltage, the biggest driving power for 6 w (2 Ω, BTL load, THD < 10%), audio range total harmonic distortion noise is less than 1%. XPT9812 application circuit is simple, just a handful of peripheral devices, integrated feedback resistance; Output don't need external coupling capacitance and buffer network.

The XPT9812 ESOP packaging, especially suitable for large volume, small weight portable system. XPT9812 interior has overheating automatic shutoff protection mechanism; XPT9812 feedback resistance built-in, through the configuration peripheral parameters can adjust the voltage amplifier gain and best sound effect, convenient application. Is your USB subwoofer and microphone perfect solutions.
