... Philips Semiconductors Programmable analog compandor DESCRIPTION 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 ...

... Philips Semiconductors Programmable analog compandor SA572 BASIC APPLICATIONS Description The SA572 consists of two linearized, temperature-compensated gain cells ( G), each with a full-wave rectifier and a buffer amplifier as shown in the block diagram. The two channels share a 2.5V common bias reference derived from the power supply but otherwise operate independently ...
