Hi, I've revised things as you suggested.. Now waiting for the DRDY pulse before sending the RDATA command and reading the data.. Still getting strange results. (Se attached photo)
For some strange reason values above a certain value trigger this type of response... A few notes
Same thing whether operating in 16Bit or 24Bit modes
Values much higher than the glitch point can be obtained by setting the PGA to a higher gain setting (Rules out any digital processing problem)
Occurs regardless of sample speed or spi clock
Any ideas would be hugely appreciated.. Were behind schedule and really hoping to get this wrapped...
VREF and AVDD is +3.3V Unipolar
