Is it possible to add AD243x nodes to an existing AD242x -bus?

  • That's a great question.  AD242x and AD243x devices are 100% compatible so yes, they can reside on the same A2B bus.   But just a few additional words of explanation might be helpful.   We generally recommend to position high power 243x nodes closest to the main node -- to minimize total system power consumption.  And in mixed node systems, the total number of nodes supported on a single daisy chain is 11 -- which is the upper limit for 242x based networks.   For this reason, we highly recommend moving completely to a 243x-based network if maximizing node count is a design objective.
