Some of the text files within the PDF file

XPT8871 is a no FM interference, AB / D class optional power amplifier. 5V operating voltage, the maximum drive power of 5W (2Ω, BTL load, THD <10%), the total harmonic distortion within the audio range of less than 1%.

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

XPT8871 with MSOP / SOP / ESOP / DFN package, especially for small volume, small weight in the portable system. Can be controlled by entering the sleep mode, thereby reducing power consumption. XPT8871 internal with overheating automatic shutdown protection mechanism; stable, gain bandwidth product up to 2.5MHz, and unity gain stability. Feedback resistor built-in, by configuring the external parameters can adjust the amplifier’s voltage gain and the best sound quality, easy to use.

2. High output power (THD + N <10%, 1KHz frequency):
3. ESOP package for the 5W (2Ω load) and 3.5W (3Ω load), 3W (4Ω load)
4. Power-down mode leakage current is small
5. Using MSOP / SOP / ESOP / DFN package
6. External gain adjustable, integrated feedback
7. Wide operating voltage range of 2.0V-5.0V
8. No need to drive the output coupling capacitor, bootstrap capacitor and buffer network unity gain stability
9. Compatible with LM4871
