Low EMI, 2.8-W Mono Filterless Class-D Audio Power Amplifier with Auto-Recovery DESCRIPTION The EUA2036 is a high efficiency, 2.8W 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, EUA2036 is capable of driving 4Ω speaker load at a continuous average output of 2.8W/10% THD+N or 2.2W/1% THD+N. The EUA2036 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 84%. In cellular handsets, the earpiece, speaker phone, and melody ringer can each be driven by the EUA2036.
