| Pin | Name | Description | |-----|------|----------------------| | 1 | VCC | Supply voltage (5 V) | | 2 | GND | Ground | | 3 | VOUT | Analog output | The MC1458 is a high-performance

| Symptom | Possible Cause (from datasheet) | Fix | | :--- | :--- | :--- | | Output stuck at 0.2V or VCC-0.2V | Magnetic field too strong (saturation) | Increase air gap or use weaker magnet | | Output fluctuates wildly | Poor power supply decoupling | Add 0.1µF cap directly at VCC/GND | | Output doesn't change with field | Wrong magnet orientation | South pole increases voltage; North decreases. Ensure field is perpendicular | | Output drifts slowly over time | Temperature change | Recalibrate quiescent point or use differential measurement | | Output voltage > VCC | Inductive kick from long wires | Add series 1kΩ resistor at output |
