Description
These monolithic integrated circuits are designed
for metallic body detection by sensing variations
in high frequency Eddy current losses. Using an
externally-tuned circuit, they act as oscillators.
The output signal level is altered by an
approaching metallic object.
The output signal is determined by supply current
changes. Independent of supply voltage, this
current is high or low, according to the presence
or absence of a closely located metallic object.
