Description
The AH8500 is a low power/micropower linear Hall effect sensor with an 8-bit output resolution. The output voltage is ratiometric to the supply voltage and proportional to the magnetic flux density perpendicular to the part marking surface. The output null voltage is at half the supply voltage.
AH8500 has a typical sensitivity of 2.1mV/G and 3.55mV/G at 1.8V and 3V. The typical null voltage offset is less than 1% of VDD. The device has a typical input referred rms noise of 0.36G and 0.24G at 1.8V and 3.0V.
