How do I interface to multiple AD719x ADCs over the same serial interface ?
Hi RobK
ok i now understand your point but the main question is while doing such thing regarding the DRDY pin ..........
the DRDY pin gets low after the conversion is available and will be waiting to be read but by this way it will not be read immediately after it gets low there will be some lagging time due to the presence of multiple ADCs but will that be ok with the AD719X ?
waiting for the DRDY pin to get low for 10 ADCs will vary the lagging time between waiting for the DRDY to get low and reading the data......aren't there a maximum time between these two actions and the data will then be lost after?
