Their versatility and wide sensing range makes them an excellent choice for a variety of analog sensing applications including industrial and automotive position, speed, and current sensors. The sensors are configured as inherently temperaturepensating Wheatstone bridges. AA-Series sensors are magnetometers, which detect absolute magnetic field. AB-Series sensors are differential gradiometers, which detect field gradients. Three magnetometer subtypes are available: the standard AA-Series; the ultrasensitive “H” subtype; the high-field, kilooersted range “K” subtype, and the low-hysteresis “L” subtype. Packages are as small as an ultraminiature 1.1 x 1.1 mm ULLGA4.
