EUA2005 Datasheet (Eutech Microelectronics) - 1.5-W Mono Filterless Class-D Audio Power Amplifier

EUA2005, 1.5-W Mono Filterless Class-D Audio Power Amplifier

The EUA2005 is a high efficiency, 1.5W 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, EUA2005 is capable of driving 8Ω speaker load at
