SA572N是一款双通道，高性能的增益控制电路，其中无论信道可被用于动态范围压缩或扩展。每通道有一个全波整流器

以检测输入信号的平均值，一个线性化，温度补偿的可变增益单元（△G ）和一个动态时间常数缓冲器。该缓冲区允许独立

控制动态攻击和恢复时间少的外部组件和改进低频增益控制纹波失真在先前的扩器。在NE572旨在用于降噪高性能的音频系统。

它也可以在宽范围的通信中使用系统和视频记录应用。

SA572N应用：

•状态变量滤波器

The NE572 is a dual-channel,

high-performance gain control circuit in which

either channel may be used for dynamic

range compression or expansion. Each

channel has a full-wave rectifier to detect the

average value of input signal, a linearized,

temperature-compensated variable gain cell

(∆G) and a dynamic time constant buffer. The

buffer permits independent control of

dynamic attack and recovery time with

minimum external components and improved

low frequency gain control ripple distortion

over previous compandors.

The NE572 is intended for noise reduction in

high-performance audio systems. It can also

be used in a wide range of communication

systems and video recording applications.
