The polarity of the Hall plate versus the output signal is programmable by the PLATEPOL parameter.
The sensitivity is programmable with 3 bits for ROUGHGAIN and 10 bits for FINEGAIN in analog output
application from 50 to 300 V/T (91206-High-Field version) and from 100 to 700 V/T (Low-Field version).
The FINEGAIN resolution depends on the programmed ROUGHGAIN setting. It typically ranges from
0.25V/T (ROUGHGAIN=7) up to 0.01V/T (ROUGHGAIN=0)
Note: Power consumption is 2mA less if ROUGHGAIN
