EUA2011 Datasheet (Eutech Microelectronics) - 3-W Mono Filterless Class-D Audio Power Amplifier

EUA2011, 3-W Mono Filterless Class-D Audio Power Amplifier

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
