Forum Post: ADS131M02-Q1: Question about ADS131M02-Q1 sample error

Part Number: ADS131M02-Q1 1.When i write CH1_CFG regs MUX1 [1:0] is 01b,i get a channel value is FFA417. Then, I write this value into CHI_OCAL regs, i I didn't get an expectation. So, I want to know how to get offset error to write into CHI_OCAL regs. 2.I want to know how to get gain error to write into CHI_GCAL regs, I know how the error is translated into the register, but do not know how to get g ain error . 3.Whether the noise error can be eliminated. 4.How to use this DC Block Filter ,I can't calculate a COEFFICIENT. 5.I would like to know if the minimum accuracy of this adc can reach 0.2uv. Because we are used to measure the current of 100uΩ shunt resistance, 0.1uV is 1mA. Whether this accuracy will be disturbed by noise. Looking forward to your reply, thank you
