The TPA2011D1 is a 3.2-W high efficiency filter-free class-D audio power amplifier (class-D amp) in a 1.21 mm × 1.16 mm wafer chip scale package (DSBGA) that requires only three external components.
Features like 95% efficiency, 86-dB PSRR, 1.5 mA quiescent current and improved RF immunity make the TPA2011D1 class-D amp ideal for cellular handsets. A fast start-up time of 4 ms with no audible turn-on pop makes the TPA2011D1 ideal for PDA and smart-phone applications. The TPA2011D1 allows independent gain while summing signals from separate sources, and has a low 20 μV noise floor.
