Texas Instruments DRV425 precision fluxgate magnetic field sensor is designed for single-axis magnetic field sensing applications such as linear position sensing, current sensing in busbars, over-rail current detection, and general-purpose magnetic field sensors. The sensor enables galvanic isolation, high sensitivity, and accurate DC and AC field measurements.
The device provides an integrated fluxgate sensor (IFG) and internal compensation coils to support a high-precision sensing range of ± 2mT. It also has a measurement bandwidth up to 47kHz. This sensor provides low offset, offset drift and sensor noise. The output of the DRV425 is an analog signal proportional to the sensed magnetic field.
The company states that the combination of the precise gain provided by the internal compensation coil, low gain drift and very low non-linearity results in unparalleled magnetic field measurement accuracy.
