Datasheet
This document introduces STEVAL-IFS005V1, a metal body proximity detector based on the TDA0161, which features a 10 mA output current, a supply voltage of +4 V to +35 V, and a 10 MHz oscillator frequency
User Manual
TDA0161 is a monolithic integrated circuit designed by Texas Instruments for metallic body detection by detecting the variations 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.
