TDA0161DP IC - Proximity Detector IC for Metal Detection

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. Features:- • 10mA Output Current • Oscillator Frequency 10MHz • Supply Voltage +4 to +35V Specification:- Symbol Parameters Rating Units VCC Supply Voltage 35 V TJ Operating Temperature Range 150 °C TSTG Storage temperature range –55 to 150 °C Related Document:- TDA0161DP IC Data Sheet
