AD673 GROUNDING CONSIDERATIONS The AD673 provides separate Analog and Digital Common connections. The circuit will operate properly with as much as 200 mV of common-mode voltage between the two commons. This permits more flexible control of system common bussing and ...

In systems where this read-write interface is used, at least 30 microseconds (the maximum conversion time) must be al- lowed to pass between starting a conversion and reading the re- sults. This delay or “time-out” period can be implemented in ...
