I have a question regarding the tuning of Magsense.
In the application note MagSense Inductive Sensing it is said that the IDAC Value should be set to 70% of the full scale of raw count.
But there is no information at what the full scale value of the raw count is. Therefore setting the IDAC value without auto-calibration is difficult.
I understand that due the oversampling the full scale of the raw counts increase with the number of subsamples.
For more information about how i can calculate or know the full scale value of the raw counts i would be very pleased.
Solved! Go to Solution.

Hi sefu_4636006,
The MaxCount is given by ,
MaxCount = (NSub * modClk)/ LxClock
Example, if NSub = 100, ModClk = 48 Mhz, LxClk = 1 Mhz -> MaxCount = 4800.
The above formula is derived from the Max value of NsubConv that can be set
