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

General Description

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.

EUA2005 1.5-W Mono Filterless Class-D Audio Power Amplifier DESCRIPTION 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 a continuous average output of 1.5W/10% THD+N or 1.3W/1% THD+N. The EUA2005 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 EUA2005.
