CRD44800-ST-FB

www.DataSheet4U.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. This reference design uses the the ST Micro STA500, an integrated power stage back end for digital amplifiers (four STA500 parts configured as full-bridges are used for this eight-channel design). Current limiting and thermal protection are provided by the STA500. The inductor/capacitor 2nd order low pass filter (LPF) removes high frequency components from the output signal effectively converting it from digital to analog.
