AW8110CSR中文资料D 类、防破音、超低EMI、单声道、无需滤波器数据手册Awinic规格书

描述 Description

The AW8110 is a Non-Crack-Noise (NCN),Ultra-Low-EMI, filter-free, 3W, mono, Class-Daudio amplifier. Unique NCN function, whichadjusts the system gain automatically whiledetecting the “Crack” distortion of output sig-nal, protects the speaker from damage at highpower levels and brings the most comfortablelistening experience to the customers.The AW8110 features the EEE (EnhancedEmission Elimination) function which greatlyreduces EMI over the full bandwidth. TheAW8110 achieves better than 20dB marginunder FCC limits with 24 inch of cable.The filter-free PWM architecture and internalgain setting reduces external componentscount, board area consumption, system costand simplifies the design. In addition, TheAW8110 offers efficiencies above 90%. Theover-current, over-temperature and under-voltage protection is prepared inside of thedevice.
