Description
The ratiometric linear Hall effect sensor each

contain a monolithic integrated circuit on a
single chip. The 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
