Superior digital audio amplification, such as the CS4525 Class D audio amplifier, is the key to a great sounding docking station. The CS4525 remains the only one-chip digital audio solution for docking station applications because it integrates a stereo analog-to-digital converter, sample-rate converter, digital audio processor and a complete 30-watt Class D amplifier, including the controller and power stage. It supports both incoming analog and digital audio signals, and its highly efficient power stage eliminates the need for a heat sink in system designs.
