SS495B

SS495B is a SS490 series, small, versatile, linear hall-effect sensor IC which is 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 ±%, sensitivity upto ±3%) and temperature compensation. It responds 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. It is used in applications such as industrial, medical.
