Programmier set ic 922/13/2023 ![]() ![]() Rail-to-rail operation (over full voltage range) provides a more usable signal for higher accuracy. The positive temperature coefficient of the sensitivity (+0.02%/☌ typical) helps compensate for the negative temperature coefficients of low-cost magnets, providing a robust design over a wide temperature range. The quad Hall sensing element minimizes the effects of mechanical or thermal stress on the output. ![]() They respond to either positive or negative Gauss, monitoring either or both magnetic poles. Laser-trimmed, thin film resistors provide high accuracy (null to ±%, sensitivity up to ☓%) and temperature compensation. The integrated circuitry provides increased temperature stability and sensitivity. The ratiometric output voltage is set by the supply voltage and varies in proportion to the strength of the magnetic field. The SS490 Series are small, versatile, linear Hall-effect devices which are operated by the magnetic field from a permanent magnet or an electromagnet. ![]()
