TDA0161FPT

Sensor And Detector Interfaces Overview

The TDA0161FPT is a monolithic integrated circuit designed for metallic body detection by sensing variations in high-frequency eddy current losses. It operates as an oscillator using an externally tuned circuit, where the output signal level changes upon the approach of a metallic object. The device functions within a supply voltage range of +4V to +35V and draws 1mA when remote and 10mA when close. It features an oscillator frequency of 10MHz and provides a 10mA output current capability.

Sensor And Detector Interfaces Feature Summary

• Detects metallic bodies via high-frequency eddy current loss variations
• Acts as an oscillator with output determined by supply current changes
• Provides independent supply voltage operation with distinct current states

Sensor And Detector Interfaces Applications

• Metallic object proximity detection systems
• Industrial sensor interfaces requiring eddy current sensing
• Automated machinery safety interlocks

Sensor And Detector Interfaces Procurement Notes

Verify the specific suffix FPT indicates tape and reel packaging for surface mount assembly. Confirm the component status as discontinued or obsolete through official STMicroelectronics channels before finalizing procurement plans. Ensure compatibility with existing inventory management systems regarding end-of-life notifications.

Sensor And Detector Interfaces Selection Notes

Select this component for applications requiring simple, robust metallic detection without complex digital interfaces. Evaluate external coil requirements based on desired detection ranges from 2mm to 10mm. Consider the SO-8 package constraints for thermal management and board space limitations in dense assemblies.
