9.5 V高能效內(nèi)嵌DSP的D類(lèi)音頻放大器

TFA9891是一款具有先進(jìn)的揚(yáng)聲器升壓和保護(hù)算法的高效率D類(lèi)音頻放大器。它可以在3.6 V電源電壓時(shí)為8 Ω揚(yáng)聲器提供7.2 W峰值輸出功率。內(nèi)部升壓轉(zhuǎn)換器將電源電壓提升至9.5 V，為充分提升音質(zhì)提供了充足余量。\r\n\r\n與競(jìng)品解決方案不同，自適應(yīng)聲音激勵(lì)器算法使用反饋來(lái)同時(shí)精確計(jì)算溫度和振幅，從而使TFA9891適應(yīng)聲學(xué)環(huán)境中的變化。

9.5V升壓內(nèi)嵌DSP的D類(lèi)音頻放大器

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 m ? 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/;
