9.5 V高能效内嵌DSP的D类音频放大器

TFA9890A是一款具有先进的扬声器升压和保护算法的高效率D类音频放大器。该器件可在电源电压为3.6 V时向8 Ω扬声器提供7.2 W的峰值输出功率。内部升压转换器可将电源电压提升到9.5 V，为充分提升声质提供了充足余量。\r\n\r\n各种工况下都能为扬声器提供安全的工作环境。TFA9890A可在确保振膜位移和音圈温度不超过其额定极限的同时实现最大的声音输出。此功能基于可在所有扬声器环境（例如自由空气、密闭盒或通风盒）中运行的音箱模型。 此外，先进的信号处理功能可确保音频信号的质量不会因放大器或扬声器中的不必要削波或失真而降低。\r\n\r\n与其他解决方案不同，自适应声音激励器算法使用
