General Description

The CS4525 is a stereo analog or digital input PWM high efficiency Class D amplifier audio system with an integrated stereo analog-to-digital (A/D) converter. The stereo power amplifiers can deliver up to 15 W per channel into 8Ω speakers from a small space-saving 48-pin QFN package. The PWM amplifier can achieve greater than 85 efficiency. The package is thermally enhanced for optimal heat dissipation which eliminates the need for a heatsink.
