AW8155FCR中文资料D 类、防破音、超低EMI、超强TDD抑制数据手册Awinic规格书

描述 Description

The AW8155 is a non-crack-noise (NCN), ul-tra-low-EMI, filter-free, AB/D output mode selection, second generation Class-D audio amplifier. Ultra low THD+N,Unique NCN func-tion, which adjusts the system gain automati-cally while detecting the “Crack” distortion of output signal, protects the speaker from damage at high power levels and brings the most comfortable listening experience to the customers.
AW8155 NCN output power can be set to 0.65w or 0.85w for different speakers, this feature is embedded in order to protect speakers from damage caused by an exces-sive sound level.
The AW8155 features a unique RNS and net audio technology, which effectively reduces RF energy, attenuate the RF TDD-noise, an acceptable au-dible level to the customer.
The AW8155 features the EEE (Enhanced Emission Elimination) function which greatly reduces EMI over the full bandwidth. The AW8155 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. The over-current, over-temperature is prepared inside of the device.
The AW8155 is available in an ultra small 1.5mm×1. 5mm FC-9 package. The AW8155 is specified over the industrial temperature range of -40℃ to +85℃.
