Programmable Analog Compandor SA572 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, temperaturecompensated variable gain cell (DG) 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 g

SA572 Features
