The AW8155A is a non-crack-noise (NCN), ultra-low-EMI, filter-free, AB/D output mode selection, unique RNS and net audio tech-nology, second generation Class-D audio amplifier. Ultra low THD+N,Unique NCN function, which adjusts the system gain au-tomatically while detecting the “Crack” distor-tion of output signal, protects the speaker from damage at high power levels and invites the user to bask in immense musical enjoy-ment.
AW8155A 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 AW8155A features a unique RNS and net audio technology, which effectively reduces RF energy, attenuate the RF TDD-noise, an acceptable audible level to the customer.
The AW8155A features the EEE (Enhanced Emission Elimination) function which greatly reduces EMI over the full bandwidth. The AW8155A 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 AW8155A is available in an ultra small 1.5mm×1.5mm FC-9 package. The AW8155A is specified over the industrial temperature range of -40℃ to +85℃.
