Quad Hall sensing element for stable
output
SS490SeriesMRL(MiniatureRatiometric
Linear) sensors have a ratiometric output
voltage, set by the supply voltage. It var-
ies in proportion to the strength of the
magnetic field.
A new Hall effect integrated circuit chip
provides increased temperature stability
and sensitivity. Laser trimmed thin film
resistors on the chip provide high accu-
racy (null to
±
3%, sensitivity up to
±
3%)
and temperature compensation to re-
