HI ,
I am trying to use Magsens to develop a linear position sensor. Since the Magsense does not support linear sition application, I have to decode the value of the raw count and apply it for linear position sensor. so my question is :
what is raw count? like is it the voltage amplitude of the LC tank or it is the inductance or current( because of the IDAC)? I am realy confused. As described in datasheet "The change in Vamp is proportional to the change in inductance seen at the LC tank circuit." then what is relation between Vamp and raw count?
Solved! Go to Solution.

Hi
The raw count of the sensor is the digital measurement of the LC tank amplitude, Vamp.
Please refer to the "Inductive sensing design guide" for more details on MagSense.

The working principle of Magsense is that a change in inductance of the LC tank causes a change in VAMP resulting in a change in the raw count of corresponding channels.
Thanks and regards
