IC693PWR331 功率放大器的技術指標

　　1.額定功率

　　是指連續的正弦波功率，在1kHz正弦波輸入及負載下，諧波失真小於1%所輸出的功率，表示成W/CH（瓦/聲道），一般來說，額定功率越大，造價越高。

　　2.總諧波失真

　　是指高次諧波佔基波的百分比，總諧波失真越小越好，好的功率放大器的總諧波失真能達到0.02%

　　3.轉換率

　　單位時間上升的電壓幅度，單位為伏/微秒，它反映了功率放大器對瞬態聲音信號的跟蹤能力，是一種瞬態特性指標。

　　4.阻尼因子

　　其定義為功率放大器的負載阻抗（大功率管內部電阻加上音箱的接線線阻），例如8Ω：0.04Ω=200：1，一般要求比值比較大，但不能太大，太大會覺得揚聲器發聲單薄，太小則會使聲音混濁，聲音層次差，聲像分布不佳。

　　5.輸出阻抗

　　通常有8Ω、4Ω、2Ω等值，此值越小，說明功率放大器負載能力越強。就單路而言，額定負載為2Ω的功率放大器，可以帶動4只阻抗為8Ω的音箱發聲，並且失真很小。
