SS490 Series MRL (Miniature Ratiometric
Linear) sensors have a ratiometric output
voltage, set by the supply voltage. It varies
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 accuracy
(null to ±3%, sensitivity up to ±3%)
and temperature compensation to reduce
null and gain shift over temperature.
The quad Hall sensing element minimizes
the effects of mechanical or thermal
stress on the output. The positive temperature
coefficient of the sensitivity
(+0.02%/°C typical) helps compensate
for the negative temperature coefficients
of low cost magnets, providing a robust
design over a wide temperature range.
