Figure 2 shows the complete schematic of the INA253Ax test board. The functional pins are accessed
through test points. The IS+ and IS– pins are shorted to VIN+ and VIN– using 0-Ω resistors, respectively.
The reference pins are in the split supply configuration through installed 0-Ω resistors Rx03 and Rx06.
