The TPA2011D1 is a 3.2 W high efficiency filterless Class D audio power amplifier in a 1,21 mm × 1,16 mm wafer-scale package (WCSP) that requires only three external components (Class D amplifier).

Features of 95% efficiency, 86 dB power supply rejection ratio, 1.5 mA quiescent current, and improved immunity make RF ideal for mobile phone TPA2011D1 Class D amplifiers. With a fast start-up time of 4 milliseconds, the no-sound turn-on popularity makes it ideal for PDAs and smartphones to use the TPA2011D1. The TPA2011D1 allows independent gain, while summarizing, signals from different sources, and has a low noise layer of 20μV.
