Non-Crack-Noise, Ultra-Low-EMI, 3W, Mono, Filter-Free, Class-D Audio Amplifier

The AW8110 is a Non-Crack-Noise (NCN), Ultra-Low-EMI, filter-free, 3W, mono, Class-D audio amplifier. Unique NCN function, which adjusts the system gain automatically while detecting the “Crack” distortion of output sig- nal, protects the speaker from damage at high power levels and brings the most comfortable listening experience to the customers. The AW8110 features the EEE (Enhanced Emission Elimination) function which greatly reduces EMI over the full bandwidth. The AW8110 achieves better than 20dB margin under FCC limits with 24 inch of cable. The filter-free PWM architecture and internal gain setting reduces external components count, board area consumption, system cost and simplifies the design. In addition, The AW8110 offers efficiencies above 90%. The over-current, over-temperature and under- voltage protection is prepared inside of the device.
