AD8317 Datasheet Log Detector/Controller

Manufacturer: Analog Devices

Datasheet Details

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 used in either measurement or controller modes.
