XPT4863

Features

Product Name: Class AB Audio Amplifier

Product model: XPT4863

Product Description:

XPT4863 is a Class AB, dual-channel bridge audio power amplifier chip, powered by a 5.0V power supply; when THD+N is less than 10%, it can provide 3W of power to a 4Ω load. In addition, when connected to stereo headphones, XPT4863 drives stereo headphones in single-ended working mode. It is a classic chip that is generally recognized and widely used in the market.

The XPT4863 dual-channel audio power amplifier is designed for systems that need to output high-quality audio power. It uses surface mount technology and external feedback resistors. Only a small number of peripheral devices are needed to enable the system to have high-quality audio output power. The XPT4863 dual-channel design enables the chip to have two working modes: bridge-connected speaker amplification and single-terminal stereo headphone amplification, simplifying the peripheral circuit design of the audio system.

XPT4863 uses an externally controlled low-power shutdown mode, a stereo headphone amplification mode, and an internal thermal shutdown protection mechanism. It also uses the characteristics of the circuit to reduce noise (ticking and popping) and distortion.
