AD7416/AD7417/AD7418
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’ e d together to form a common interrupt

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.
