Product Summary

The SA571N is an Audio Amplifier. It is a versatile low cost dual gain control circuit in which either channel may be used as a dynamic range compressor orexpandor. Each channel has a full-wave rectifier to detect theaverage value of the signal, a linerarized temperature-compensatedvariable gain cell, and an operational amplifier. The SA571N is well suited for use in cellular radio and radio communications systems, modems, telephone, and satellite broadcast/receive audio systems.
