Product Description
OH490 Series Linear Hall Switch IC
The OH490 series are high-precision linear Hall switch ICs featuring Rail-to-Rail output for accurate measurements. The output voltage linearly varies with magnetic flux density, enabling detection of subtle magnetic field changes. These ICs are suitable for applications such as motion, distance, and position sensing, and can perform reliably in harsh or polluted environments. Key features include good linearity, high sensitivity, Rail-to-Rail output, and the ability to sense both positive and negative magnetic fields.

Usage Notes
- The basic design principle is that the static output voltage (B=0GS) is half of the supply voltage. For a 5V operating voltage, the midpoint voltage is approximately 2.5V. When the S pole is aligned with the Hall circuit face, the output voltage increases above the midpoint. When the N pole is aligned, the output voltage decreases below the midpoint. The output voltage range is approximately 0-5V.
- The recommended operating voltage is 5V.
- This circuit is suitable for detecting magnetic fields in the hundreds of Gauss. For larger or smaller magnetic fields, please consult for alternative Hall element models.
