4. Typically it is recommended to us a 56resistor for R1 and R2 and a 2.2μF E-Cap capacitor for C1, C2 and C3. These values may
need to be optimized depending on the coils used.
To help with IC protection it’s advised to add a Zener diode between Vdd and ground. The Zener diode should be chosen to help
prevent the supply voltage exceeding the maximum rating of the device.
