Overview
The TDA0161FP, produced by STMicroelectronics, is a monolithic integrated circuit designed for metallic body detection. This component senses variations in high-frequency eddy current losses, making it suitable for proximity detection applications. The TDA0161FP operates as an oscillator when connected to an externally-tuned circuit, and the output signal level changes in response to an approaching metallic object. This device is versatile and can be used in various environments due to its wide supply voltage range and robust operating temperature conditions.
