IC693PWR331 功率放大器的技术指标
1.额定功率
是指连续的正弦波功率,在1kHz正弦波输入及负载下,谐波失真小于1%所输出的功率,表示成W/CH(瓦/声道),一般来说,额定功率越大,造价越高。
2.总谐波失真
是指高次谐波占基波的百分比,总谐波失真越小越好,好的功率放大器的总谐波失真能达到0.02%
3.转换率
单位时间上升的电压幅度,单位为伏/微秒,它反映了功率放大器对瞬态声音信号的跟踪能力,是一种瞬态特性指标。
4.阻尼因子
其定义为功率放大器的负载阻抗(大功率管内部电阻加上音箱的接线线阻),例如8Ω:0.04Ω=200:1,一般要求比值比较大,但不能太大,太大会觉得扬声器发声单薄,太小则会使声音混浊,声音层次差,声像分布不佳。
5.输出阻抗
通常有8Ω、4Ω、2Ω等值,此值越小,说明功率放大器负载能力越强。就单路而言,额定负载为2Ω的功率放大器,可以带动4只阻抗为8Ω的音箱发声,并且失真很小。
