The SS490 Series MRL (Miniature Ratiometric Linear) sensors are small,
　　versatile linear Hall effect devices which are operated by the magnetic field
　　from a permanent magnet or an electromagnet. The ratiometric output
　　voltage is set by the supply voltage and varies in proportion to the strength
　　of the magnetic field.
　　The integrated circuitry provides increased temperature stability and
　　sensitivity. Laser trimmed thin film resistors provide high accuracy (null to ±
　　3%, sensitivity up to 3%) and temperature compensation. These linear
　　position sensors have an operating temperature range of -40?C to +150 C,
　　appropriate for industrial and automotive environments. They respond to
　　either positive or negative gauss, monitoring either or both magnetic poles.
　　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. Rail-to-rail operation (over full voltage
　　range) provides a more usable signal for higher accuracy.

　　The recent extension to the product line, the SS490B Series, offers cost-
　　effective MRL sensing solutions with slightly wider specifications than the
　　SS490 high-performance products. Like the SS490 Series, the SS490B
　　has a typical sinking or sourcing output of 1.5 mA continuous, uses 7 mA of
　　supply current at 5.0 volts and 25?C, and provides predictable performance
　　over the full temperature range. The SS490B Series sensors have wider
　　null and sensitivity tolerances and a wider drift over temperature.
　　The SS490B Series sensors are a new lower cost product line extension.
　　They complement the SS490 Series of small size, high accuracy and high
　　performance miniature linear products.
