Robust package capable of
withstanding harsh environments
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
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 decrease in response to a north
pole (negative) magnetic field.
These 3150U & 3151U ratiometric linear Hall
effect sensors can be used as contactless
sensors for rotary and linear position sensing
and for current sensing. The devices in this
series are similar in performance except for
their allowable quiescent voltage output
change over the specified operating
temperature range.
