hello,
L9966 datasheet (§8.2) mentions a max total resistance measurement accuracy of 1.5% (if CALIB_SEL=1).
It seems that such accuracy does not include external pull up RRx accuracy which should impact the overall measurement accuracy and therefore going above 1.5%, if I am not wrong.
I am seeing that "no ratiometric comparator is running" (talking about VDD5REF I suppose).
Please, how could I foresee the impact of RR1/RR2/RR3 accuracy on overall measurement accuracy?
How could I get rid off the VDD5REF variations, maybe by enabling this ratiometric comparator, how to enable it?
Thanks beforehand.
