    Problem of the DELSIG OFFSET

              I am making a design for test of DELSIG-ADC, Basically it's working, Then I think how to get more precise resolution. Finally want to compensate the offset. But which radix of the offset? In actual ADC value? Or converted value to u/m/ V? I don't know, One reason is no offset value has not able to get. Even It seems has some offset value, But always these value are ZERO, Is it OK? Configuration: [ resolution: 20bit, rate: 10/sec, continuous conversion, input mode: single-end, buffer mode: rail-to-rail, range: 0-6*vref, Vref: 1.024v ] Regards, Happy ADC
