PROXIMITY DETECTORS
Minidip
ORDERING NUMBER : TDA0161DP
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.
