3 說明
TAS6424E-Q1 器件是一款采用 2.1MHz PWM 開關頻率的四通道數字輸入 D 類音頻放大器，以非常小的 PCB 尺寸實現成本優化的解決方案，可針對啟停事件在低至 4.5V 的電壓下全面運行，并可在高達 40kHz 的音頻帶寬下提供出色的音質。
輸出開關頻率既可以設置為高于調幅 (AM) 頻帶，以消除 AM 頻帶干擾并降低輸出濾波需求及成本；也可以設置為低于 AM 頻帶，以優化器件效率。
該器件具有內置負載診斷功能，用于檢測和診斷誤接的輸出，以及檢測交流耦合的高頻揚聲器，以幫助縮短制造過程中的測試時間。
器件增加了 EMI 管理特性（包括展頻、輸出相位偏移和優化的壓擺率），以幫助應對系統級 EMI 挑戰。
TAS6424E-Q1 D 類音頻放大器專為汽車音響主機和外部放大器模塊而設計。有關引腳兼容的單通道、雙通道及四通道器件，請參閱器件選項表。
