General Description

The AW8110 is a Non-Crack-Noise (NCN),

Ultra-Low-EMI, filter-free, 3W, mono, Class-D

audio amplifier. Unique NCN function, which

adjusts the system gain automatically while

detecting the “Crack” distortion of output sig-

nal, protects the speaker from damage at high

power levels and brings the most comfortable

listening experience to the customers.

The AW8110 features the EEE (Enhanced

Emission Elimination) function which greatly

reduces EMI over the full bandwidth. The

AW8110 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

AW8110 offers efficiencies above 90%. The

over-current, over-temperature and under-

voltage protection is prepared inside of the

device.

The AW8110 is available in an ultra small

1.45mm×1.45mm

CSP9

package.

The

AW8110 is specified over the industrial tem-

perature range of -40℃ to +85℃.
