com CRD44800-ST-FB 60 W Full-Bridge Reference Design for the CS44800 Features Eight full-bridge channels, 60 W each Programmable load compensation Power Supply Rejection (PSR) feedback allowing amplifier to operate from low cost linear unregulated power supplies Peak signal limiting Thermal and over-current protection > 85% amplifier efficiency Works with GUI to configure the board or in a standalone mode for easy operation.
Demonstrates recommended layout and grounding arrangements 10% THD+N).
A 155 W Switched Mode Power Supply (SMPS) is used to power the CRD44800-ST-FB.
As shown below, the CS44800 IC takes four stereo digital audio inputs in I²S format and converts them to PWM outputs.
This 64-pin LQFP IC provides an integrated sample rate converter for 32 kHz-192 kHz input sample rate support, volume up/down, speaker load compensation, peak limiting to prevent amplifier clipping, power supply ripple compensation, and AM frequency interference elimination.
