TPA2011D1 

It is 1.2W mono Class D automatic recovery short-circuit protection

illustrate   The TPA2011D1 is a 3.2 W high-efficiency filterless Class D audio power amplifier in a 1,21 mm × 1,16 mm wafer-level package (WCSP) that requires only three external components (Class D amplifier). The 95% efficiency feature, 86 dB power supply rejection ratio, quiescent current of 1.5 mA and improved immunity make RF ideal for mobile phones TPA2011D1 Class D amplifiers. The fast boot-up time of 4 milliseconds and the silent turn-on pop make it ideal for TPA2011D1 PDA and smartphone applications. TPA2011D1 allows independent gain while summarizing signals from different sources and has a low noise layer of 20 μV.   characteristic   Powerful mono Class D amplifier 3.24 Watts (4,5 V, 10% THDN) 2.57 watts (4,5 volts, 1% THDN) 1.80 watts (8,5 volts, 10% THDN) 1.46 watts (8,5 volts, 1% THDN) Comprehensive feedback resistance K table 300 For DAC integrated image suppression filter noise reduction Low output noise of 20μV Low quiescent current of 1.5 milliamps Automatic recovery of short-circuit protection Overheating protection 9 balls, 1,21 1,16 mm mm× 0,4 mm pitch WCSP apply Wireless mobile phones and handheld computers or Portable navigation device Portable audio equipment in general
