Following up on my SPI issue, has anyone worked with the TI TLV1570 ADC? This is the part that I'm actually interfacing with via SPI.

I'm now bit-banging SPI and the scope tells us that everything looks good, yet we're getting absolutely nothing back from the TLV1570. We initially were getting back constant high voltage on MISO from the TLV1570 and eventually concluded it might be a bad part. So we swapped it out for a new TLV1570 and now we're getting back a constant low voltage on MISO.

I'm more a software guy than anything and we're pretty much concluding that they must have the part wired wrong, but does anyone have any insight on this? Does the TLV1570 need to be wired in any special way? Is there anything I need to be aware of when communicating with this part?

Unfortunately I'm writing this from the hotel which means I'm staying yet another night. :(
