AD8319 Datasheet (Analog Devices) - Log Detector/Controller

AD8319, Log Detector/Controller

The AD8319 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
