**Part Number:**AMC1100

Dear TI team,

Good evening.

We are measuring AC voltage of 50KHz switching frequency and fundamental frequency of 50Hz at input side of AMC1100,which is very noisy.(Kindly find the attached images of waveform.doc)

We are not getting proper AC voltage shape and its flattening, so we assume is it because of gain error?

We wish to reduce 50KHz switching frequency ripples by placing ferrite bead across a resistor as per below image,

In that case if we place ferrite bead across 332k resistor then net Series resistance also changes.So we need to make changes in Voltage divider circuit to keep input voltage range

with in +/-250mV range.Right?

If we place ferrite bead across the resistor,is below calculation still applies?

Thank you,

Girish K
