I read circuit note CN-0383 and I plan on using AD7124-8 to interface 4 2-wires RTDs for ratio-metric measurement.
One thing I can't figure out is what conversion mode to use on AD7124-8, and what will be achievable sampling rate.
If I understand correctly, I'm going to have to enable IOUT current to the RTD I want to measure before each measure, since IOUT0 and IOUT1 attributions can't be part of an "ADC Setup".
Is it correct to assume that "continuous read mode" is out of the question in this configuration ?
In the case of "continuous conversion mode", shall I reconfigure IOUT0 or IOUT1 for the next RTD measurement before reading the data register ?
What is the best mode to use in order to achieve maximal SPS, and what will be that maximum SPS ?
Thanks for your help !
