hello sir,

 

We are facing issue with SIGMA DELTA  ADC.of MKM34Z256VLQ7 current{A} parameter measurment for genset application

Now at input side our voltage range is 0-500mV. (AC voltage) 

We as of now we have taken average of the readings and we are getting readings but the values are much more varying with the same input value .

So we can't able to handle it .

Please help with the same problem
