EUA2036 Datasheet | Eutech Microelectronics

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 ponent 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 pared to a typical class AB amplifier. With a 3.6V supply driving an 8Ω speaker , the efficiency for a 400m W power level is 84%. In cellular handsets, the earpiece, speaker phone, and melody ringer can each be driven by the EUA2036. The gain of EUA2036 is externally configurable which allows independent gain control from multiple sources by summing signals from separate sources. The EUA2036 is available in space-saving WCSP and TDFN packages.
