Asahi Kasei Microdevices HQ-0A11 InAs Quantum Well Hall Element

Asahi Kasei Microdevices HQ-0A11 InAs Quantum Well Hall Element is designed to output an electric signal according to the strength of the magnetic field created by the magnet. This hall element includes 0.66mV/mA/mT sensitivity, 6V maximum input voltage, 8.5mA maximum input current, and 600Ω minimum input resistance. The HQ-0A11 InAs quantum hall element features a 16% better Signal-to-Noise (S/N) ratio directly correlated to position detection accuracy. This device operates at a temperature range of -40°C to 125°C and offers a small and thin package size of 0.8mm x 0.4mm x 0.23mm. Typical applications include paper thickness detection, smartphone cameras, detection with joysticks, magnetic encoder, wheel rotation speed detection, and lens modules.
