AD606 80 dB Demodulating Logarithmic Amplifier

The AD606 is a complete, monolithic logarithmic amplifier using a 9-stage “successive-detection” technique. It provides both logarithmic and limited outputs. The logarithmic output is from a three-pole post-demodulation low-pass filter and provides a loadable outpu.
