DRV425RTJT .

产品概述

The DRV425RTJT is an Integrated Fluxgate Sensor (IFG) with an internal compensation coil, designed for single-axis magnetic field-sensing applications and enables electrically isolated, high-sensitivity and precise DC- and AC-field measurements. 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 unrivalled magnetic field measurement precision. The output of the DRV425 is an analogue 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.
