Current monitor for a High frequency signal

by user7994   Last Updated September 11, 2019 22:25 PM

I'm working on a current monitoring circuit for a high frequency current monitoring application as shown in the schematic below, the requirements are as follows.

  1. Should be able to provide RMS current feedback, the differential amplifier output would be fed into an ADC
  2. the AC signal feeds into a resistor which connects to ground

will the LM7372 connected directly across the shunt work for this application? or is there filtering required before connecting to the LM7372 to get the RMS value?
