XPT9911 power amplifier


XPT9911 is a no FM interference, AB / D class optional (D class when the anti-broken sound) power amplifier. The maximum output power is up to 12W (2Ω, BTL load, THD <10%), and the total harmonic distortion noise in the audio range is less than 1%. XPT9911 application circuit is simple, only a very small number of peripheral devices, integrated feedback resistor; output does not require external coupling capacitor or bootstrap capacitor and buffer network.
