TDA0161FP

Sensor And Detector Interfaces Overview

The TDA0161FP 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 delivers a 10mA output current. Key electrical parameters include an oscillator frequency of 10MHz and a negative resistance capability on terminals A and E of up to 4kΩ. The component is housed in an SO-8 surface-mount package.

Sensor And Detector Interfaces Feature Summary

• Detects metallic bodies through high-frequency eddy current loss variations
• Acts as an oscillator with output determined by supply current changes
• Provides independent operation from supply voltage fluctuations
• Features high or low current states based on metallic object proximity

Sensor And Detector Interfaces Applications

• Metallic object presence detection systems
• Industrial automation sensors
• Proximity monitoring circuits

Sensor And Detector Interfaces Procurement Notes

Verify the specific suffix 'FP' confirms the SO-8 plastic package type when ordering. Confirm the temperature range specification aligns with system requirements. Check for availability status as older components may have limited stock. Ensure external coil and capacitor values match the required detection distance specifications.

Sensor And Detector Interfaces Selection Notes

Select this component for applications requiring simple, robust metallic detection without complex digital interfaces. Consider the need for external tuning components such as coils and capacitors to set the oscillation frequency. Evaluate the required detection range against the available coil configurations provided in the datasheet. Ensure the operating environment supports the specified temperature range.

Sensor And Detector Interfaces Part Context

The TDA0161 series includes variants like the TDA0161DP (DIP-8) and TDA0161FPT (SO-8 Tape and Reel). The TDA0161FP specifically denotes the SO-8 tube packaging option. All variants share identical electrical characteristics and functionality, differing only in physical package form factor and shipping configuration.

Sensor And Detector Interfaces Replacement Considerations

No direct public substitute part numbers are documented for the TDA0161FP. Designers must evaluate alternative proximity detector ICs that support similar oscillator-based metallic detection principles and comparable supply voltage ranges.
