描述 Description

The AW8011 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 AW8011 features the EEE (Enhanced Emission Elimination) function which greatly reduces EMI over the full bandwidth. The AW8011 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 AW8011 offers efficiencies above 90%. The over-current and over-temperature is prepared inside of the device. The AW8011 is available in an ultra small WLCSP 1.25mmX1.185mmX0.582mm-9B package. The AW8011 is specified over the industrial temperature range of -40℃ to +85℃.
