PRODUCTION DATA
The excitation signal is generated by an LC oscillator. The LCIN and LCOUT pins will be connected to the excitation coil. The oscillator signal driver automatically regulates the signal to VAMP_LC. The user can adjust the external capacitors on LCIN and LCOUT to select the excitation frequency. For best performance, TI recommends to use two capacitors. Place one capacitor from LCIN to ground and place the other capacitor from LCOUT to ground (C1 and C2) instead of using only one capacitor between LCIN and LCOUT.
Use Equation 1 to calculate the excitation frequency.
