商品介紹
◎ SS49x Series MRL (Miniature Ratiometric Linear) sensors have a ratiometric output voltage, set by the supply voltage.
◎ It varies in proportion to the strength of the magnetic field.
◎ A new Hall effect integrated circuit chip provides increased temperature stability and sensitivity.
◎ Laser trimmed thin film resistors on the chip provide high accuracy and temperature compensation to reduce null and gain shift over temperature.
◎ The quad Hall sensing element minimizes the effects of mechanical or thermal stress on the output.
◎ The positive temperature coefficient of the sensitivity helps compensate for the negative temperature coefficients of low cost magnets, providing a robust design over a wide temperature range.
◎ Small size
◎ Low power consumption
◎ Single current sinking or current sourcing linear output
◎ Built-in thin-film resistors - laser trimmed for precise sensitivity and temperature compensation
◎ Rail-to-rail operation provides more useable signal for higher accuracy
◎ Responds to either positive or negative gauss
◎ Quad Hall sensing element for stable output)
