EUA2011 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...
