Question
I am currently using the AD7792 converter on a board together with some other
devices on the common SPI bus, however when designing I didn't realize that the
AD7792 will pull it's DOUT pin low whenever a conversion is complete. Wont
there be a collision if I happen to talk to another device on the bus?.
Answer
The AD7792 will pull its DOUT low as this line also acts as a data rdy line,
the only way around this when using multiple devices on the one serial bus is
to de-select the device using the /CS..
CS can be used to select the ADC in systems with more than one device on the
serial bus.
