Analog linear devices are sensors that produce an output voltage that varies linearly with respect to the input magnetic field. These devices may be sensitive to either a single polarity or to either polarity magnetic field. Sensitivity is shown in units of mV/mT, and input referred noise is modeled as part of the device response.

Many of these devices are ratiometric, therefore, the sensitivity varies with the supply voltage. This is particularly helpful when using the supply voltage as the reference voltage of an ADC to help minimize the effect of VCC fluctuations on the measurement accuracy. Once the VCC voltage has been entered, and the user clicks outside of the input field, the sensitivity updates accordingly.
