Description

The AW8057E 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 AW8057E integrates spread spectrum functionality, which can effectively improve EMI performance and features the EEE(Enhanced Emission Elimination) function which greatly reduces EMI over the full bandwidth. The filter-free PWM architecture reduces external components count, board area consumption, system cost and simplifies the design. In addition, AW8057E offers efficiencies above 86.5%. The over-current, over-temperature protection is prepared inside of the device. The AW8057E is available in a SOP-8L package. The AW8057E is specified over the industrial temperature range of -40℃ to +85℃.
