2.4 Jumper and Vref Input Information

The output of the INA630 is given by: Vout = Vin∙Gain + Vref. When JMP1 is in the GND position, the INA630 REF pin is connected to GND (see Figure 2-2). When JMP1 is in the NC position the Ref input (J8) is used to apply and external reverence voltage (see Figure 2-3). By default R6 is not installed, so any signal applied to J8 is directly applied to the INA630 Vref pin. The resistors R5 and R6 can be used as a voltage divider to set the Vref signal (see Figure 2-4).
