Description

The AW8058 is a ultra-low-EMI, RNS, mono, filter-free, Class-D audio amplifier. Unique RNS, which effectively reduces RF energy, attenuate the RF TDD-noise, an acceptable audible level to the customer. The AW8058 features the EEE(Enhanced Emission Elimination) function which greatly reduces EMI over the full bandwidth. The AW8058SPR 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, AW8058 offers efficiencies above 87%. The over-current, over-temperature protection is prepared inside of the device. The AW8058 is available in a MSOP-8L package. The AW8058 is specified over the industrial temperature range of -40℃ to +85℃.
