Tiny Hall element delivers InAs sensitivity

The HQ0A11, an indium arsenide (InAs) Hall element from AKM, is the smallest and thinnest in the company’s high-sensitivity HQ series. At just 0.8×0.4×0.23 mm, the HQ0A11 reduces volume by 85% compared to its predecessor, the HQ0811. It also delivers approximately 16% better signal-to-noise ratio, directly improved position detection accuracy and making its S/N performance the highest in the HQ lineup.

Hall elements are commonly used in position detection for image stabilization and autofocus in smartphone cameras. According to AKM, the HQ0A11 significantly reduces lens-shake effects, particularly with telephoto lenses. Its compact size also makes it well-suited for high-density component mounting in limited spaces.

The HQ0A11 achieves a sensitivity of 0.66 mV/mA/mT, with noise kept at 1.51 µVRMS/mA. It is expected to contribute to enhanced performance, not only in smartphone camera modules, but also in small motors for robots.

AKM has begun mass production and shipment of the HQ0A11 InAs Hall element.
