Description
The AH8503 is a high accuracy, 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.
AH8503 is a trimmed device with typical sensitivity of 2.25mV/G and 3.8mV/G at 1.8V and 3V respectively with an accuracy of 3% at +25°C. The device has a typical input referred rms noise of 0.36G and 0.24G at 1.8V and 3.0V.
