Hall Effect Sensor 10mA 1.8V/2.5V/3.3V 6-Pin U-DFN2020 T/R

The AH8501 is a high accuracy, 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. AH8501 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.Designed for battery powered consumer equipment to office equipment, home appliances and industrial applications, the AH8501 can operate over the supply range of 1.6V to 3.6V and uses an externally controlled ENABLE pin clocking system to control operating modes and sampling rates to minimize the power consumption. The typical average operating supply current is between 8.9µA during sleep mode and 1.16mA at maximum sampling rate at 1.8V. With a conversion pulse every 50ms at the ENABLE pin, the device achieves a micropower operation with the power consumption of 22µW typical at 1.8V supply.To minimize PCB space the AH8501 are available in small, low profile U-DFN2020-6.
