LM4663 2 Watt Stereo Class D Audio Power Amplifier with Stereo Headphone Amplifier
General Description
The LM4663 is a fully integrated single supply, high efficiency Class D audio power amplifier solution.
The LM4663 utilizes a continuous time delta-sigma modulation technique that lowers output noise and THD when compared to conventional pulse width modulators. The LM4663 also features a stereo headphone amplifier that delivers 80mW into a 32 headset with less than 0.5% THD. The LM4663 has two stereo inputs that can be selected to drive either the headphone amplifier or the Class D amplifier. All amplifiers are protected with thermal shutdown. In standby mode, the LM4663 draws an extremely low 2µA supply current. With a 4 load, the IC's efficiency for a 250mW power level is 69%, reaching 83% at a power level of 2W. The IC features click and pop reduction circuitry that minimizes audible poppi
