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 temperaturecompensating 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. 1 NVE Corporation 11409 Valley View Road, Eden Prairie, MN 55344-3617 Phone: (952) 829-9217 sensor-apps@ nve.com www.nve.com ©NVE Corporation AA/AB-Series Analog Magnetic Sensors Absolute Maximum Ratings Parameter AAxxx/ABxxx/AAL002 Supply voltage AAHxxx/AAKxxx/ABHxxx/ AAL004/AAL024 Operating temperature AAxxx/AAKxxx/ABxxx/AALxxx AAHxxx/ABHxxx Storage temperature AAxxx/AAKxx/ABxxx/AALxxx AAHxxx/ABHxxx ESD (Human Body Model) Applied magnetic field Voltage from sensor connections to center pad (applies to TDFN package only) Symbol VCC H Min. −50 −65 −65 Max. 24 12 125 150 135 150 400 Unlimited 63 Units Volts °C °C °C Volts Tesla Volts DC 2 NVE Corporation 11409 Valley View Road, Eden Prairie, MN 55344-3617 Phone: (952) 829-9217 sensor-apps@ nve.com www.nve.com ©NVE Corporation AA/AB-Series Analog Magnetic Sensors Operating Specifications Parameter Supply voltage AAHxxx/AAKxxx/ ABHxxx/AAL004 AAxxx/ABxxx/AAL002 Operating temperature AAKxxx AAxxx/ABxxx/AALxxx AAHxxx/ABHxxx Electrical AAxxx/AAKxxx/AALxxx/ABxxx offset AAHxxx/ABHxxx Output at maximum field AAxxx/ABxxx AAHxxx/ABHxxx AAKxxx AALxxx Nonlinearity AAxxx/AAKxxx/ABxxx/AAL002 AAHxxx/ABHxxx/AAL0x4 AAHxxx/ABHxxx Hysteresis AAxxx/AAKxxx/ABxxx AALxxx Resistance tolerance Resistance vs. temperature AAxxx/ABxxx AAHxxx/AAKxxx/ AALxxx/ABHxxx AAxxx/ABxxx AAHxxx/ABHxxx AAKxxx Output AALxxx temperature AAxxx/ABxxx coefficient AAHxxx/ABHxxx AAKxxx AALxxx AAKxxx AAKxxx .
