I am trying to optimize AD7745 conversion modes and filters. Below are a couple configurations I have
1. Longest conversion time and continuous conversions
2. Longest conversion time and single conversion
3. Shortest conversion time and continuous conversions
4. Shortest conversion time and single conversion
Also, I have only single excitation input and one Cin.
All (1), (2) and (3) configurations reading are far off from the actual cap while
(4) is very closed (10% off).
I wonder my setups have some issues and why the shortest conversion time and single conversion
has better data.
I am looking forward to hearing from you.
