Digital Linear

Digital Linear devices include an ADC as part of the device, and therefore are able to output conversion results in units of LSB/mT. These devices require a VCC voltage to perform simulations, but also allow the user to select from programmable settings such as sensitivity range (which is set using the drop-down option for "Maximum Input"), temperature compensation, and over-sampling averages. Increasing the total number of samples used to complete a conversion increases the effective number of bits (ENOB) of the ADC and results with a less observed noise in the output measurement.

Output for these devices is converted to an integer output code depending on the device mode selected. It is important to remember that with averages set to '1' that the standard conversion result may be 12-bit, while increasing averages above this value typically produce a 16-bit result.
