Solid State Hall Effect Sensors
High Performance Miniature Ratiometric Linear
SS490 Series
FEATURES
• Small size (.160 x .118 in)
• Power consumption of 7 mA
at 5 VDC for energy
efficiency
• Single current sinking or
current sourcing output
• Linear output for circuit
design flexibility
• Built-in thin film resistors are
laser trimmed for precise
sensitivity and temperature
compensation
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 -40C 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 25C, 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.
