onfigured as a 4-element
wheatstone bridge, these
magnetoresistive sensors
convert magnetic fields to
a differential output volt-
age, capable of sensing
magnetic fields as low as
30
µgauss.
These MRs
offer a small, low cost,
high sensitivity and high
reliability solution for low
field magnetic sensing.

FEATURES AND BENEFITS
Wide Field Range
Field range up to
±6
gauss, (earth’s field = 0.5 gauss)
Small Package
• Designed for 1- and 2-axis to work together to provide 3-axis (x, y, z) sensing
• 1-axis part in an 8-pin SIP or an 8-pin SOIC or a ceramic 8-pin DIP package
• 2-axis part in a 16-pin or 20-pin SOIC package
Solid State
These small devices reduce board assembly costs, improve reliability and ruggedness com-
pared to mechanical fluxgates.
Patented on-chip set/reset straps to reduce effects of temperature drift, non-linearity errors and
loss of signal output due to the presence of high magnetic fields
Patented on-chip offset straps for elimination of the effects of hard iron distortion
The sensors were specifically designed to be affordable for high volume OEM applications.
