DESCRIPTION AND FEATURES

Product Introduction

1.LM4863 is a dual BTL (Bridge-Tied Load) audio power amplifier IC that delivers stable gain output. When powered by a 5 V supply, it can continuously provide 3 W of undistorted output power with THD+N (Total Harmonic Distortion plus Noise) below 1.0%. In addition, it can operate in single-ended (SE) mode to drive stereo headphones or be used as a preamplifier.

2.LM4863 is designed for audio systems and uses SMT (Surface-Mount Technology), simplifying the peripheral circuitry of audio designs. With only a small number of external components, the system can achieve high-quality audio output.

3.LM4863 features an externally controlled low-power shutdown mode, a stereo headphone amplifier mode, and an internal thermal shutdown protection mechanism. These characteristics significantly improve SNR (Signal-to-Noise Ratio) and reduce distortion.

4.LM4863 includes an internal thermal shutdown protection circuit, enabling long-term stable operation and reducing the risk of damage or burnout.
