CS4525

Highly optimized for flat-panel digital television and docking station applications, the CS4525 is an innovative, highly integrated single-chip Class D Amplifier.

The CS4525 is notable 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.

Also CS4525 featured is an on-board digital audio processor, offering such features as parametric equalization, auxiliary output for lip-sync delay and bass management. In addition to stereo configurations that provide 15 watts per channel output, the IC can support 2.1-channel configurations (2 X 7.5 watts per channel plus 1 X 15 watts) as well a low-frequency effects configuration (1 X 30 watts). Additionally, Cirrus Logic offers OEMs a companion IC, the CS4412, which is a cost-effective power-stage only IC.
