SA571D属于集成电路（IC）的音频专用。由安森美半导体制造生产的SA571D音频专用音频专用的半导体器件专为音频信号的滤波、驱动、放大、转换和接口而设计。特征包括功能、应用、通道数、接口、电压和规格。应用包括音频系统、汽车音频、消费类音频、乐器、专业音频、通信系统、电信系统、数字音频、驱动器、前置放大器、信号混合、信号处理、语音触发器解决方案和 10 Base-T。

The SA571 is a versatile low cost dual gain control circuit in which either channel may be used as a dynamic range compressor or expandor. Each channel has a full−wave rectifier to detect the average value of the signal, a linerarized temperature−compensated variable gain cell, and an operational amplifier.

The SA571 is well suited for use in cellular radio and radio communications systems, modems, telephone, and satellite broadcast/receive audio systems.
