Adjusting Threshold With Fixed Resistor

Another option for setting BOP is to place a resistor on footprint R7 (see Figure 4-1). The R7 resistance is the resistance seen between the ADJ and GND pin of the TMAG5328. You must select a resistance within the 2kΩ to 15kΩ range.

If the user wants to select the fixed resistor option for setting BOP, then remove the jumper on J3 so that the DAC, potentiometer or anything else that is not connected to the ADJ pin.
