FEATURES Small size （。160 × .118N）
Low power consumption - typically mA at 5 VDC Single current sinking or current
Sourcing linear output Built-in thin-film resistors - laser trimmed for precise
sensitivity and temperature compensation Rail-to-rail operation provides more useable
signal for higher accuracy Operating temperature range of -40 to +150 C Responds
to either positive or negative gauss
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.
