SA572
Programmable Analog
Compandor
The SA572 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 SA572 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.
