SYSTEM WITH MULTIPLE AD7416 DEVICES

The three LSBs of the AD7416 serial address can be set by the

user, allowing eight different addresses from 1001000 to

1001111. Figure 25 shows a system in which eight AD7416

devices are connected to a single serial bus, with their OTI

outputs wire-AND’ed together to form a common interrupt

line. This arrangement means that each device must be read to

determine which one has generated the interrupt, and if a

unique interrupt is required for each device, the OTI outputs

can be connected separately to the I/O chip.
