Hello team,
Regarding TIC12400, customer is using analog function, in datasheet ± 1V ground offset needs to be considered, what will be the cause of this ground offset? must be considered?
Because for a multi-gear analog switch, considering the ground offset, there would be a gap interval greater than 2V between adjacent gears, but this is difficult to achieve for multi-gear switches.
Thanks!

Daniel Wang
Hi Daniel,
Thank you for your question. Can you let me know where in the datasheet you are referring to?
Thank you, Amy
Hi Daniel,
Thank you for sharing this. The non -Q1 datasheet doesn't mention it and that is what I was looking at.
The ground shift comes from the switch reference point and the ground reference of the TIC12400-Q1. This is what causes the up +/- 1V ground shift in the system and why there may be up to a +/- 1V of potential difference. As an example, refer to the specifications as outlined in Table 9-4/9-5.
Thanks,
Amy
