Product Summary

The SA571N is a versatile low cost dual gain control circuit in which either channel may be used as a dynamic range compressor or expandor. Each channel of the SA571N has a full-wave rectifier to detect the average value of the signal, a linerarized temperature-compensated variable 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.

Parametrics

SA571N absolute maximum ratings: (1) VCC Maximum operating voltage: 18 VDC; (2) TA Operating ambient temperature range: -40 to +85°C; (3) PD Power dissipation: 400mW.

Features
