Their versatility and AA-Series AB-Series Magnetometer Gradiometer wide sensing range makes them an excellent choice for a Transfer Function Transfer Function variety of analog sensing applications including industrial and automotive position, speed, and current sensors. The sensors are configured as inherently temperature- compensating 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.

AA/AB-Series Analog Magnetic Sensors Operation Sensor Subtypes There are four AA/AB-Series subtypes, as summarized in the table below. “H” subtypes are designed for very high sensitivity, and “K” types have low sensitivity and high saturation for high-field sensing. “L” types offer low hysteresis. AAH-Series parts also have a 150°C maximum temperature specification. AAxxx/ AAHxxx/ Parameter ABxxx ABHxxx AAKxxx AALxxx Field Sensitivity High Very High Low High Operating Field Range High Low Very High Medium Hysteresis Medium High Medium Low Max. Temperature High Very High Commercial High Magnetometer Operation AA-Series sensors are magnetometers, which detect the absolute magnetic field. Direction of Sensitivity Unlike Hall effect or other sensors, the direction of sensitivity of GMR sensors is in the plane of the package, which more convenient for many applications. Two permanent magnet orientations that will activate the sensor are shown in Figure 1: Figure 1. Planar magnetic sensitivity. Omnipolar AA-Series sensors are “omnipolar,” meaning the output is equally sensitive to either magnetic field polarity and the output is always a positive voltage: Output Field Figure 2. The omnipolar response of AA-Series sensors. Standard and Cross-Axis Axis Directional Sensitivity The standard axis of sensitivity is along the part axis, but there are some parts available with cross-axis sensitivity, and AAKxxx sensors are not directionally sensitive in the IC plane, and are therefore sensitive in both standard and cross-axis axis directions. 4 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 Illustrative Applications Traditional Differential Amplifier Traditional differential amplifiers use low-cost op-amps to provide a single-ended analog output. The circuit below has a gain of 20, which provides a full-scale output at slightly less than the sensor’s saturation. A low-cost, low bias current op amp allows large resistors to avoid loading the sensor bridge. The 250 KΩ input resistors are 100 times the 2.5 KΩ sensor output impedance to avoid loading.

Sensor Instrumentation Amplifier Instrumentation amplifiers such as the INA826 are popular bridge sensor preamplifiers because they have a low component count and have excellent common-mode rejection ratios without needing to match resistors. These amplifiers can run on single or dual supplies. AC coupling can be used for small, dynamic signals. The circuit below has a gain of 20. The general equation for the output voltage is: VOUT = (1+ 49.4K / RG)VIN + VREF ; VIN = VOUT+ − VOUT- 3-24V Sensor RG=(cid:13) 2.6K + 20 x V OUT REF - INA826 Figure 10. Single-ended analog sensor instrumentation amplifier. Note that the instrumentation amplifier has a minimum output of 0.1V, so to detect very low fields on a single supply, an offset can be provided by using a non-zero V .

AA/AB-Series Analog Magnetic Sensors Constant-Current Sensor Drive Using a constant current rather than conventional constant voltage sensor supply can significantly improve temperature stability of AAxxx/ABxxx sensors. AA00x sensors, for example, have an output temperature coefficient (TC ) of 0.03%/°C with constant O-I current, versus −0.1%/°C with constant voltage (TC ). O-V A simple constant-current supply is illustrated below: 3-16V 10K VDD VDD/2 + = VDD/2Rcc TLV271 - V+ 10K OUT- OUT+ V- 6K Rcc AAxxx/ABxxx Figure 11. Constant-current supply. The supply current for the circuit above is V /2R . R can be set to the maximum sensor bridge resistance (e.g., 6 KΩ for many cc cc cc sensors) to provide the highest possible output without saturating the op-amp. The sensor will be driven with 1 mA for a 12 V supply in the circuit above. Similar op-amp or instrumentation amplifiers can be used for constant-current or constant-voltage supplies. Variable Threshold Magnetic Switch NVE offers AD-Series factory-set GMR Switches, but AA-Series analog sensors can be used for special thresholds or hysteresis, or for variable thresholds. In this circuit, the threshold is varied by changing R , which sets the gain of the differential amplifier. G The 1 MΩ resistor sets the threshold hysteresis: 3-5.5V AA-Series Sensor 8 1 5 100K 240K 1M + 4 OUT + RG=(cid:13) 10K 1nF - REF MCP6541 - INA826 100K 50K 1nF Figure 12.

AA/AB-Series Analog Magnetic Sensors LED Field-Strength Indicator The op-amp circuit in Figure 13 below can be used to change the brightness of an LED to indicate magnetic field strength at a glance: 3V-16V R = LED V / I SENSOR-MAX LED-MAX AAAAxxxxxx - VDD 2 mA max. + TLV272 - VOUT-MAX 50K Offset - + + GND Figure 13. LED brightness indicates the magnetic field. The LED current is proportional to the sensor output: I = (V − V ) / R LED OUT+ OUT- LED The maximum LED current can be set to the maximum sensor output. For example, for an AAK001, typical V is 25 mV/V, OUT-MAX so for a three-volt supply the maximum is approximately 75 mV. For a high-efficiency with a forward current of 2 mA, R = 75 mV / 2 mA = 38Ω. LED The 50 KΩ potentiometer is optional, to correct for sensor offset or to set the minimum field to turn on the LED. The 16-volt maximum supply voltage noted in Figure 13 is limited by the op-amp selected, but note that some sensors have a 12-volt maximum supply rating. The three-volt minimum supply is to provide enough voltage to turn on the LED; the sensors can operate on lower voltages. Noncontact Current Sensing AA-Series sensors are often used to measure the current over a circuit board trace. The sensor measures the current by detecting the magnetic field generated by the current through the trace. The AAL024 is ideal for this application because its cross-axis sensitivity provides sensitivity to a current trace directly under the part, and its low hysteresis provides repeatability. The AA003-02 is popular for overcurrent protection where hysteresis is needed and high accuracy is not required. Typical current sensing configurations are shown below: Figure 14a. 0.09" (2.3 mm) trace Figure 14b. 0.05" (1.3 mm) trace Figure 14c.
