Precision AGC circuit using an AD531 multiptter/divider and an AD741 op amp. The circuit works by rectifying a signal and comparing it with thevoltage at the set level pot. The comparator output is then applied as a control signal to the AD531. The circuit can regulate VOUT to 3 volts peak to peak for inputs from 0.4 volt peak to peak to 6.0 volts peak to peak from 30 hertz to 400 kilohertz (courtesy Analog Devices, Inc.).
