Dear forum members,
i use a K60 ADC in 16bit differential mode with VREFH = 3,3V and VREFL = 0V. The DM-Input is connected to 1,65V (fix voltage) and the DP-Input to our Signal which goes from 0 to 3,3V.
Errata e3863 says: "DP-Input must be <3,1968V to avoid conversion errors".
So i think i have a problem with the input signal range.
Is exchanging DM and DP a possible workaround ? (then DP is fix 1,65V and DM goes from 0V up to 3,3V)
"e3863: ADC: In 16-bit differential mode, ADC may result in a conversion error when positive input is near upper rail reference voltage Errata"
"Workaround: To avoid a conversion error near positive full-scale in this mode, do not allow the input voltage on the plus-side of the differential pair (DPx) to exceed (VREFH*31/32)"
