DIODES AH49FQ-W-7

The AH49FQ from Diodes Incorporated is a small, versatile linear Hall-effect device driven by the magnetic field generated by a permanent magnet or electromagnet. The output voltage is ratiometric to the supply voltage and varies proportionally with the magnetic field strength. The IC features low-noise output, eliminating the need for external filtering components. It also incorporates precision resistors to enhance temperature stability and accuracy. These linear Hall sensors operate over a temperature range of -40°C to +105°C, making them suitable for automotive, commercial, consumer, and industrial applications. The AH49FQ is available in an SC59 package.
