SS495A - Hall sensor, linear, analogue, TO-92

MRL (miniature ratiometric linear) sensors of the SS494 series have a ratiometric output voltage determined by the supply voltage. This varies in proportion to the strength of the magnetic field. A new integrated Hall-effect circuit chip provides increased temperature stability and temperature sensitivity. Laser-matched thin-film resistors on the chip permit a high degree of accuracy and temperature compensation to reduce zero and gain shifts over temperature. A design with a quadruple Hall effect minimises the impact of mechanical and thermal stresses of the output and creates a stable output. The positive temperature coefficient for sensitivity balances out the negative temperature coefficient of lower-cost magnets for a robust design over broad temperature ranges.

• Small size • Low power consumption • Single P-switching power output or current providing linear output • Laser-matched built-in thin-film resistors provide high sensitivity and temperature compensation • Rail-to-rail operation provides a better signal for higher accuracy • Responsive to positive and negative gauss values • Fourfold Hall-effect measuring element for stable output
