ADC: Device Has Higher Offset Error Than the Design Goal (0.5 to 1%) on Some Channels

Revision(s) Affected

0 and A

Details

Based on the current data obtained on all channels, some channels show an offset error as high as 1%.

Workaround(s)

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.

Note:

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.
