描述 Description

The AW8055B is a non-crack-noise (NCN), ultra-low-EMI, filter-free, AB/D output mode selection, unique RNS technology, second generation Class-D audio amplifier. Ultra low THD+N, Unique NCN function, which adjusts the system gain automatically while detecting the “Crack” distortion of output signal, protects the speaker from damage at high power levels and invites the user to bask in immense musical enjoyment.AW8055B NCN output power can be set to 0.65w in 0.85w for different speakers, this feature is embedded in order to protect speakers from damage caused by an excessive sound level.The AW8055B features a unique RNS tech-nology, which effectively reduces RF energy, attenuate the RF TDD-noise, an acceptable audible level to the customer.The AW8055B features the EEE (Enhanced Emission Elimination) function which greatly reduces EMI over the full bandwidth. The AW8055B 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 de-vice. The AW8055B is available in a MSOP-8L Package.The AW8055B is specified over the industrial temperature range of -40℃ to +85℃.
