DRV5057 Linear Hall Effect Sensor

The DRV5057 is a linear Hall effect sensor that responds proportionally to magnetic flux density. The device can be used for accurate position sensing in a wide range of applications. The device operates from 3.3-V or 5-V power supplies. When no magnetic field is present, the output produces a clock with a 50% duty cycle. The output duty cycle changes linear.
