Description

SS490 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 (null to ¡À3%, sensitivity up to ¡À3%) 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 (+0.02%/¡ãC typical) helps compensate
for the negative temperature coefficients of low cost magnets, providing a robust
design over a wide temperature range.

Features

• Small size (.160 ´ .118N)
• Low power consumption - typically
  7 mA at 5 VDC
• 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
•  Operating temperature range of ¨C40
  to +150¡ãC
• Responds to either positive or
  negative gauss
• Quad Hall sensing element for stable
  output
