XPT8871 Datasheet – AB / D Class Audio Power Amplifier – XPT

Part Number : XPT8871, XPT8871ES

Function : AB / D switching, overtemperature & undervoltage, no FM interference + 5W (2Ω)

Package  : ESOP 8 Pin

Manufacturers : XPT ( http://www.xptek.cn/ )





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.





1. FM no interference, high efficiency, excellent sound quality

2. Output power is high (THD + N <10%, 1KHz frequency):

3. The ESOP package features 5W (2Ω load) and 3.5W (3Ω load), 3W (4Ω load)

4. Power-down mode leakage current is small

5. External gain adjustable, integrated feedback

6. Wide operating voltage range of 2.0V-5.5V

7. No need to drive output coupling capacitors, bootstrap capacitors, and buffer networks

8. Compatible with LM4871

STK412-410 datasheet, pinout

Description :

The STK412-000 series are class H audio power amplifier hybrid ICs that feature a built-in shift power  upply circuit. These Provide ICs high efficiency audio power amplification by controlling (switching) the supply voltage supplied to the power transistors according to the detected level of the input audio signal.


1. Pin compatible IC series that covers power ratings from 50 W × 2 channels to 180 W × 2 channels at 0.7 or 0.8% THD, 20 Hz to 20 kHz. This allows the use of a common PCB for all output classes.

2.  The pin arrangement is also unified with that of the three-channel STK413-000 series. This means that PCBs designed for three-channel models can also be used for two-channel models.
