AD8317 - Log Detector/Controller
The AD8317 is a demodulating logarithmic amplifier, capable of accurately converting an RF input signal to a corresponding decibel-scaled output.
It employs the progressive compression technique over a cascaded amplifier chain, each stage of which is equipped with a detector cell.
The device can be
