the thin coil (CD54 equivalent). Make sure that the current flowing into the transducer under the
specified operational conditions does not exceed the allowable current. For example, if load current
is larger than 5 mA in the above circuit, magnetic saturation occurs and the IC may be damaged at
the worst.
