We did some intensive tests with the DDC316 and noticed a signal noise due to Range Error Match (0.2%FSR typ., 1%FRS max.) between side A integrator and side B integrator of the same input.
This meas with RANGE[1:0]=11, max. input charge 12pC, we have a signal noise of 131LSB@0.2% or 655LSB@1%.
Is there any solution to eliminate this signal noise?
Would it be an option to calculate the averge of to sample (one side A and one side B sample)?
Thanks in advance.
