DESCRIPTION

These monolithic integrated circuits are designed

for metallic body detection by detecting the vari-

ations in high frequency Eddy current losses. With

an external tuned circuit they act as oscillators.

Output signal level is altered by an approaching

metallic object.

Output signal is determined by supply current

changes. Independent of supply voltage, this cur-

rent is high or low according to the presence or the

absence of a close metallic object.
