Hot-selling and scarce TPA2011D1YFFR 3.2W Mono Filter-Free Class-D Audio Power Amplifier DSBGA9 spot stock

Product Descriptions

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 (WCSP) that requires only three external components.

​

Features like 95 percent 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.
