TPA2011D1YFFR Audio Power Amplifier IC Audio Amplifiers Stereo Med Power Class-AB
1 Features
– 3.24W(4Ω,5V,10%THDN) – 2.57W(4Ω,5V,1%THDN) – 1.80W(8Ω,5V,10%THDN) – 1.46W(8Ω,5V,1%THDN)
2 Applications
3 Description The TPA2011D1 is a 3.2-W high efficiency filter-free class-D audio power amplifier (class-D amp) in a 1.21mm × 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. Device Information
