UPA2008 3W STEREO CLASS-D AUDIO POWER AMPLIFIER

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-pa.
