DRV425/DRV425-Q1 Fluxgate Magnetic Field Sensor Texas Instruments DRV425/DRV425-Q1 Precision Fluxgate Magnetic Field Sensor is designed for single-axis, magnetic-field sensing applications. This sensor enables electrically isolated, high-sensitivity, and precise DC- and AC-field measurements. The device provides an integrated fluxgate sensor (IFG) with an internal compensation coil to support a high-accuracy sensing range of ±2mT. It also has a measurement bandwidth of up to 47kHz. This sensor provides a low offset, offset drift, and noise of the sensor. The precise gain, low gain drift, and very low nonlinearity provided by the internal compensation coil result in unrivaled magnetic-field measurement precision. The output of the DRV425/DRV425-Q1 is an analog signal proportional to the sensed magnetic field. The DRV425-Q1 devices are AEC-Q100 qualified for automotive applications.
