EUA2011

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 4 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 8 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.
