9.5V升压内嵌DSP的D类音频放大器; • Boost Voltage – 9.5 V\n• Output power: 3.6 W (RMS) into 8 Ohm at 3.6 V supply voltage (THD = 1 %)\n• I2C-bus control interface (400 kHz)\n• High efficiency and low power dissipation\n• Sample frequencies from 8 kHz to 48 kHz supported in I2S mode and 16 kHz to 48kHz in PDM mode\n• 3 bit clock/word select ratios supported (32x, 48x, 64x) in I2S mode\n• Bit clock speed from 2.048 MHz up to 6.144 MHz in PDM mode\n;

The TFA9891 is a high efficiency class-D audio amplifier with a sophisticated speakerboost and protection algorithm. It can deliver 7.2 W peak output power into an 8Ohmspeaker at a supply voltage of 3.6 V. The internal boost converter raises the supplyvoltage to 9.5 V, providing ample headroom for major improvements in sound quality.\nUnlike competing solutions, the adaptive sound maximizer algorithm uses feedback toaccurately calculate both the temperature and the excursion, allowing the TFA9891 toadapt to changes in the acoustic environment.\n
