UNISONIC TECHNOLOGIES CO., LTD UPA2008 Preliminary 3W STEREO CLASS-D AUDIO POWER AMPLIFIER WITH DC VOLUME CONTROL  DESCRIPTION The UTC UPA2008 is a third generation 5-V class-D amplifier which provides precise DC volume control, lower supply current, lower noise floor, higher efficiency, smaller packaging, and fewer external components. Designed using a new filter-free class-D modulation technique, the UTC UPA2008 is capable of directly driving the speakers, without needing a low-pass output filter consisting of two inductors and three capacitors per channel. Eliminating this output filter saves approximately 30% in system cost and 75% in PCB area.
