Description

XPT8871 is a non-FM interference, AB / D class optional power amplifier. The maximum drive power is 5W (2Ω, BTL load, THD <10%) at 5V, and the total harmonic distortion noise in the audio range is less than 1%.

XPT8871 application circuit is simple, only a very small number of external devices, integrated feedback resistor; output does not require external coupling capacitors or on the lifting capacitor and the buffer network.
