3-W Mono Filterless Class-D

Audio Power Amplifier

DESCRIPTION

The EUA2011 is a high efficiency, 3W mono class-D audio

power amplifier. A low noise, filterless PWM architecture

eliminates the output filter, reducing external component

count, system cost, and simplifying design.

Operating in a single 5V supply, EUA2011 is capable of

driving 4Ω speaker load at a continuous average output of

3W/10% THD+N or 2W/1% THD+N. The EUA2011 has

high efficiency with speaker load compared to a typical

class AB amplifier. With a 3.6V supply driving an 8Ω

speaker , the efficiency for a 400mW power level is 88%.

In cellular handsets, the earpiece, speaker phone, and

melody ringer can each be driven by the EUA2011. The

gain of EUA2011 is externally configurable which allows

independent gain control from multiple sources by

summing signals from separate sources.

The EUA2011 is available in space-saving WCSP and

TDFN packages.
