D 類音訊放大器其高效率、低功耗的特點，除了為可攜式電子產品系統帶來 更長的電池壽命之外，散熱片之面積較小的優點，也讓 D 類音訊放大器在非可 攜式的應用上受重視[28]，例如 LCD 平面電視，由於 LCD 的畫面品質與其環境 溫度有相當大的關係，且平面電視空間有限，使用傳統類比功率放大器時，其散 熱設計上較為困難，若設計不良將產生熱點(hot spot)，使 LCD 顯示不平均(見 [18])。因此 D 類功率放大器在這方面的應用佔有絕對的優勢，而本平台正好提 供此方面應用之解決方法。
本文所提及之D 類放大器系統平台由於採用全橋式功率放大器，並不存在 直流偏壓，因此其效率高達83 %，較 A 類放大器的 25%及 AB 類放大器的 40~60%
高。再者由於平台採用1.5-位元運算，故於切換次數上更大幅降低，對於 MOS 元件的使用壽命以及熱能的產生皆有所改善。
綜觀平台整體效果，其適合於大功率輸出之裝置，且成本低，體積小，可應 用於手提音響，車用音響設備，以及數位電視等地方。
