Description:

Each ratiometric linear Hall-effect sensor contains a monolithic integrated circuit on a single chip. This circuit

incorporates a quadratic Hall sensing element, which minimizes the effects of mechanical and thermal stress on

the Hall element and temperature compensating circuitry to compensate for the inherent Hall element sensitivity

change over temperature current.

These ratiometric linear Hall-effect sensors provide an output voltage that varies in proportion to the applied

magnetic field. The voltage output will increase in response to a south pole (positive) magnetic field applied

perpendicular to the package symbolization face, and will decrease in response to a north pole (negative)

magnetic field.

These 3150 ratiometric linear Hall-effect sensors can be used as a non-contact sensor for rotary and linear

position sensing and for current sensing.
