Jumper Settings For ADC Gain
The ADS1115-BRVG comes with jumpers and resistor dividers that can be used to
divide the voltage seen by the analog to digital converter. This can be useful for
example when monitoring a battery voltage or some other voltage that may be
considerably higher than the power supply voltage (VDD) of the ADS1115 analog to
digital converter. The following two tables indicate which jumpers correspond to which
input channels of the ADS1115 (Table 1) and which jumper settings should be used to
achieve a given gain at the ADS1115 (Table 2).
