Hi All,
I am trying to debug the AC current measurement.
Could anybody help me out.
The differential signal across 22R is 50mv for 820mA AC load. Waveform is attached.
Now if i measure the output signal at opamp output at pin no.4 of MCP6001UT i found 3.3V square pulse.
I checked the signal at pin no 1 of opamp it is the same as output.
I checked the signal at pin no 3 of opamp it is the same as output.
Our idea do design this circuit was we have given DC biasing to 1.65V and AC should be superimpose to DC and then we can get output from opamp pin-4.
But this idea is not working at all.

So please help me.
