TDA0161DP

Sensor And Detector Interfaces Overview

The TDA0161DP 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 provides a supply current change to indicate presence: approximately 10 mA when a target is close and 1 mA when remote. It supports a supply voltage range of +4 V to +35 V and features a 10 mA output current capability with an oscillator frequency up to 10 MHz. The component is housed in an 8-pin DIP package.

Sensor And Detector Interfaces Procurement Notes

Verify the specific suffix DP indicates the DIP-8 tube packaging configuration. Confirm the operating temperature range matches the design requirements. Ensure the external coil and capacitor values align with the desired detection distance specifications provided in the datasheet application tables.

Sensor And Detector Interfaces Selection Notes

Select this component for applications requiring simple, robust metallic proximity detection without complex digital interfaces. Consider the required detection range and adjust the external coil inductance and capacitance accordingly. Evaluate the need for Litz wire versus single wire coils to optimize sensitivity and parallel resistance characteristics for the specific environment.

Sensor And Detector Interfaces Part Context

The TDA0161 series includes variants such as the TDA0161FP (SO8) and TDA0161FPT (SO8 Tape and Reel). The TDA0161DP specifically denotes the DIP-8 package version. All variants share identical electrical characteristics and functionality, differing only in physical packaging and shipping format.

Sensor And Detector Interfaces Replacement Considerations

No direct public substitute part numbers are documented for the TDA0161DP. Designers must evaluate alternative proximity detector ICs that support similar oscillator-based eddy current detection principles and comparable supply voltage ranges.
