The SN2010 is a 2.6W high efficiency filter-free class-D audio power amplifier in a 1.5 mm × 1.5 mm wafer chip scale package (WCSP) that requires only three external components.

Operating in a single 5V supply, SN2010 is capable of driving 4Ω speaker load at a continuous average output of 2.6W@10% THD+N or 2.1W@1% THD+N. The SN2010 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 88%.

In cellular handsets, the earpiece, speaker phone, and melody ringer can each be driven by the SN2010. The gain of SN2010 is externally configurable which allows independent gain control from multiple sources by summing signals from separate sources.
