The DRV425 is designed for single-axis magnetic field-sensing applications, and enables electrically-isolated, high-sensitivity, and precise dc- and ac-field measurements. The device provides the unique and proprietary, integrated fluxgate sensor (IFG) with an internal compensation coil to support a high-accuracy sensing range of ±2mT, with a measurement bandwidth of up to 47kHz. The low offset, offset drift, and noise of the sensor, combined with 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 is an analog signal proportional to the sensed magnetic field.

The device offers a complete set of features, including an internal difference amplifier, on-chip precision reference, and diagnostic functions to minimize component count and system-level cost.

The device is available in a thermally-enhanced, nonmagnetic, thin WQFN package, with a thermal pad for optimized heat dissipation, and is specified for operation over the industrial temperature range of –40°C to +125°C.
