Description
AI
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 ±2 mT with a measurement bandwidth of up to 47 kHz. 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 DRV425 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 DRV425 is available in a thermally-enhanced, non-magnetic, thin WQFN package with a PowerPAD™ for optimized heat dissipation, and is specified for operation over the extended industrial temperature range of –40°C to +125°C.
