UTC571 Linear Integrated Circuit

LI NEAR I NTEGRATED CI RCUI T The UTC571 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 has a fullwave rectifier to detect the average value of the signal, a linerarized temperature-compensated variable gain cell, and an operational amplifier. The UTC571 is well .
