Good afternoon
We aim at connecting several PCBs like in the sketch below. We've submitted this topology to TI previously on the isolation forum, and got the answer that it would work if the capacitance of both ADS7828 and the other IC (a fan controller not yet defined) is below 40pF regarding the SCL/SDA pins.
Could you please provide us this capacitance value for the ADS7828. If you see some additional comments or suggestions to do on this layout, please simply express your mind...
Thanks for your attention
David Clavier
