The sensor frequency is calculated with the following equation.
Equation 6. ![GUID-2C0862E4-7702-4693-8A26-4DC9F6FDAB1F-low.gif](/ods/images/SNOSCZ7B/GUID-2C0862E4-7702-4693-8A26-4DC9F6FDAB1F-low.gif)
where:
- ƒSENSOR is the calculated oscillation frequency with no target present
- LSENSOR is the inductance of the sense coil or reference coil
- CTOTAL is sum of external sensor, board parasitic, and pin parasitic capacitances connected to LCOM, refer to Figure 7-1
