MERUS™ D 類音訊放大器 IC、多晶片模組和分立的 MOSFET/HEMT 驅動器 IC

傳統的 D 類放大器是一種開關放大器，通常由兩個帶脈寬調製（PWM）信號的功率 MOSFET 組成。對於輸出水準超過 20 瓦的情況，需要一個 LC 濾波器，這會增加尺寸和成本。

 

隨著每個產品中的音訊通道數量不斷增加，傳統的 D 類功率放大器在緊湊型應用中面臨設計挑戰：低功率效率、過多的熱量生成（即使在中等聽音水準下），以及需要笨重且昂貴的濾波器。英飛淩的多級 D 類音訊放大器電路技術——全球首創——使其能夠在減少電磁干擾和帶外雜訊的同時，改善功耗。通過消除或最小化濾波器的使用，可以降低製造成本，從而節省設計空間。

 

憑藉革命性的多級 D 類放大器 IC，英飛淩在功率效率和功率密度方面處於領先地位。更酷、更小、更輕的 D 類音訊放大器，打造出色的音訊產品。
