I have a query relating to the ALERT pin of AD7291. I cannot find in the
datasheet whether this pin is driven by a push-pull driver or whether it is an
open-collector output? Are you able to combine the ALERT outputs of multiple
AD7291 devices into a single ALERT status?
It is a push pull driver. Open collector output should have been the right
choice. But, we have CMOS driver there as this core also supports SPI interface
