Handling Procedures
This device has built-in protection against high static
voltages or electric fields. However, due to the unique
properties of this device, anti-static precautions should be
taken as for any other CMOS component. Unless
otherwise specified, proper operation can only occur when
all terminal voltages are kept within the supply voltage
range.

Note 1:
Resonant Capacitor trimming is only offered standard for the EM4205. In case that the trimming of the resonant capacitor is
not done, tolerance range is the same as in EM4305.
