AGC circuit

Please give me some suggestion about an AGC chip for audio .
Something like a microphone preamplifier with AGC.
My question is if exist such circuits not builded with discrete (FET...) but integrated with AO.
 

Re: AGC circuit

Have a look at THAT 4301.

It's a chip that integrates 3 OPAMPS, a RMS circuit and a VCA amplifier with excellent THD (dyn. range >115dB, THD < -0.03%)

Also I am sure there was a file uploaded to the e-book section at one time which dealt with AGC but I cannot find it for now and I think it may have been for RF Agc but it would be worth some more search.

:R
