Hi Jim, I've figured out what the issue is, I just don't know how to solve it. My DVDD line is 1.8V The ADC's won't release the MISO line after their CS has been pulled up. I have 4 hooked up right now on the same line, and they all try to pull down. When I power them up individually, they work great and output as expected. But put them all on the line, and they'll fight the others when they try to speak (even when the CS lines are distributed properly). I can also verify the MISO line is not going HI-Z by tying a 1k resistor from 1.8V to MISO. The line remains at 0V, indicating it's not high impedance. Is there a configuration register I've missed for these devices to become compliant? I've checked my spi exactly matches the timing diagram given in the sheet. I've heard of things like sending a few extra clock cycles through the device after CS has been raised? Thanks, -Jake
