Product details

Overview

STEVAL-IFS005V1 from STMicroelectronics is an evaluation board built around the TDA0161 metal-body proximity detector IC, operating at 10 MHz oscillator frequency with 4–35 V supply range and 10 mA output current. It implements eddy-current sensing via an external LC tank (L1 + C1/C2), delivering voltage-independent high/low output current states based on metallic object proximity.

For engineers reviewing the STEVAL-IFS005V1 datasheet, STEVAL-IFS005V1 pinout, STEVAL-IFS005V1 application, or STEVAL-IFS005V1 equivalent, key selection criteria include its SO-8-based TDA0161 core, fixed 10 MHz oscillation, 10 mA sink capability, and compatibility with industrial position-sensing and non-contact metal detection systems requiring stable analog threshold response.

Technical Context

The board implements a self-oscillating eddy-current sensor architecture where the TDA0161 drives an external parallel LC resonator (330 µH inductor + dual 470 pF capacitors). Metallic object proximity dampens oscillation amplitude, causing measurable supply current shift.

This current shift is converted to a digital-level output via MMBT3904 NPN transistor (Q1) and 120 Ω pull-down resistor (R2), enabling direct interface with PLC inputs or microcontroller GPIOs without additional signal conditioning.

Key Specifications

Parameter	Value and Actual Design Meaning
Oscillator Frequency	10 MHz - Fixed internal timing reference for consistent eddy-current excitation and repeatable detection distance.
Supply Voltage Range	+4 V to +35 V - Enables direct integration into industrial 12/24 V DC control rails without regulation.
Output Current	10 mA - Sufficient sink drive for LED indicator (DL1) and direct connection to standard 24 V PLC input cards.
Detection Principle	Eddy-current loss modulation - Output state changes based on conductive target proximity, not magnetic permeability.
Core IC Package	TDA0161FP in SO-8 - Surface-mount footprint compatible with automated PCB assembly and thermal management up to 85°C ambient.

FAQ

What is the primary sensing mechanism used by the STEVAL-IFS005V1?

The board uses high-frequency eddy-current loss modulation: the TDA0161 excites a 10 MHz LC tank (L1 + C1/C2); approaching metallic objects dissipate energy in the coil, reducing oscillation amplitude and triggering a supply current shift that drives the output transistor stage.

Can the STEVAL-IFS005V1 detect non-ferrous metals like aluminum or copper?

Yes - it detects any electrically conductive material. Aluminum and copper produce strong eddy currents due to high conductivity; detection range depends on target size, thickness, and orientation relative to the coil axis, not magnetic properties.

Is external tuning required to operate the STEVAL-IFS005V1?

No external tuning is needed for basic operation: the board ships with optimized L1 (330 µH) and C1/C2 (470 pF each) forming a resonant tank at ~10 MHz. Adjusting these values changes sensitivity and optimal detection distance but is optional.

Does the STEVAL-IFS005V1 provide analog or digital output?

It provides a digital (two-state) output: the MMBT3904 transistor switches between saturated conduction (low output) and cutoff (high output) based on TDA0161 supply current change, yielding clean TTL/CMOS-compatible logic levels without analog signal processing.
