一般說明:MAX98357AEWL+T
MAX98357AEWL+T/ MAX98357B是易于使用,低成本,數字脈沖編碼調制(PCM)輸入D類放大器,可提供行業領先的AB類音頻性能和D類效率。數字音頻接口自動識別多達35種不同的PCM和TDM時鐘方案,無需I2C編程。消除了操作,進一步簡化了操作需要通常使用的外部MCLK信號用于PCM通訊。只需供電,LRCLK,BCLK和數字音頻生成音頻!此外,新穎的引腳排列使客戶可以使用具有成本效益的產品WLP封裝,無需昂貴的通孔(請參閱應用筆記6643:優化成本,尺寸和尺寸欲了解更多信息,請參考MAX98357AEWL+TWLP的性能)。數字音頻接口具有高度的靈活性,MAX98357AEWL+T支持I2S數據,MAX98357B支持左對齊數據。兩種IC均支持8通道時分復用(TDM)數據。數字音頻接口接受8kHz之間的指定采樣率所有支持的數據格式為96kHz。 IC可以配置為產生左聲道,右聲道或(左/ 2 +右/ 2)從立體聲輸入數據輸出。集成電路針對I2S使用16/24/32位數據進行操作并左對齊模式以及使用TDM模式的16位或32位數據。IC消除了對外部MCLK信號的需求通常用于PCM通信。除了減少電磁干擾和可能的電路板耦問題之外,減少IC的尺寸和引腳數。這些IC還具有很高的BCLK和LRCLK寬帶抖動容限(典型值為12ns),以提供強大的穩定性。操作。有源發射限制,邊沿速率限制和過沖控制電路大大降低了EMI。無過濾器擴頻調制方案消除了需求用于傳統D類設備中的輸出過濾和減少解決方案的組件數。這些IC采用9引腳WLP(1.345mm x 1.435mmx 0.64mm)和16引腳TQFN(3mm x 3mm x 0.75mm)封裝,額定溫度范圍為-40°C至+ 85°C。
