Overview
The HX49E is a miniaturized, economical, and multi-functional linear Hall effect sensor. It operates by converting an input magnetic field's strength into a proportional output voltage. At static conditions (B=0 Gs), the output voltage is half of the supply voltage. The integrated circuit features low-noise output, eliminating the need for external filtering. Precision resistors are included for improved temperature stability and accuracy. The HX49E operates within a temperature range of -40 to 105 and a supply voltage range of 3.0V to 5.5V, making it suitable for industrial, commercial, and consumer electronics. It is available in SOT-23 and TO-92S packages, both compliant with halogen-free standards.
