I Use AMC1305M05 as a sense currents in green energy system.
In no load conditon: sample rate: sinc3-16 the ripple wave about channel 1 was a little high, but the channel 2 is normal;
But i change the sample rate: sinc3-32 the ripple wave reduce quickly and the channel 2 still is normal;
i have double check the GND & VDD net is fine, the schematic are the same. so i was little confused what's the reason?
i also do load condition , the situation is same.
sinc3-16: channel 1 is bad; channel 2 is fine;
sinc3-32: channel 1 is fine; channel 2 is fine;
