Quad Hall sensing element for stable
output
SS490 Series MRL (Miniature Ratiometric
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-
duce null and gain shift over temperature.
The quad Hall sensing element minimizes
the effects of mechanical or thermal
stress on the output. The positive temper-
ature 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.
NOTICE
Products ordered in bulk packaging
(plastic bags) may not have perfectly
straight leads as a result of normal
handling and shipping operations.
Please order tape packaging option for
applications with critical lead straight-
ness requirements.
