Hello,
My customer has been using AMC1302 for current sensing. They have found AMC1302 output distortion when input is 20KHz, +/-40mV voltage signal. The gain of AMC1302 is 41. However, with the same schematic and parameter, the input signal decrease to 550Hz, we no longer see the distortion.
Could you explain what possibly cause the distortion?
This the schematic:
This is the input& output waveform:
Thanks!
Paul
