AT3503 TO-92S Hall Switch Sensor
The AT3503 TO-92S Hall Switch Sensor is an active, ratiometric linear Hall-effect sensor designed to deliver an analog output voltage that changes linearly with the applied magnetic flux density. As an active component, it requires an external power supply to function, incorporating internal circuitry such as a Hall-voltage generator, linear amplifier, signal processing units, and an emitter-follower output stage.
Features:
- Ratiometric linear analog output proportional to magnetic flux density.
- Built-in voltage regulator for stable performance and reverse polarity protection.
- High sensitivity with low-noise characteristics for accurate measurements.
- Flat frequency response suitable for dynamic applications.
- Low power consumption for energy-efficient designs.
