Omnipolar digital GMR switch sensor

The NVE AD004-00E is an omnipolar digital GMR switch sensor that integrates GMR sensing elements with onboard digital signal processing. Designed to operate at a magnetic field strength of 2 mT, it provides precise and reliable magnetic field detection. The sensor operates over a wide supply voltage range from 4.5 V to 30 V, with a low supply current of 1.8 mA, making it suitable for various power-sensitive applications. Its high-frequency response up to 250 kHz ensures accurate detection of rapid magnetic field changes. Housed in a compact MSOP8 surface-mount package, the AD004-00E is ideal for space-constrained designs. The sensor’s magnetic operate points are stable over voltage and temperature extremes, enabling high-precision, tight-tolerance magnetic sensing assemblies.
