ADC: Device Has Higher Offset Error Than the Design Goal (0.5 to 1%) on Some Channels
0 and A
Based on the current data obtained on all channels, some channels show an offset error as high as 1%.
The channel-to-channel offset error data across channels are listed in Table 5-4. This should help in calibrating in software or hardware. This was fixed in Revision B silicon.
The data provided are typical values only. These values are obtained from bench characterization at room temperature on a few devices.
TMX samples are not fully screened for all ADC parameters. If there are devices that have worse performance than suggested issues/values, it is recommended that the part be replaced.
