INA226EVM Hardware

3.5 INA226EVM Default Jumper Settings

Figure 8 shows the default jumper configuration for the INA226EVM. In general, the jumper settings of the

SM-USB-DIG Platform do not need to be changed. You may want to change some of the jumpers on the

INA226EVM board to match your specific configuration. For example, you may wish to set a specific I

address by configuring J3-J6.

Figure 8. INA226EVM Default Jumper Settings

Typically, jumper 2 on the INA226EVM is always set to the INT position. When set to the INT position, the

SM-USB-DIG Platform provides the supply for the INA226. When this jumper is set to the EXT position, an

external supply voltage can be connected to terminal strip T2 to provide the supply for the INA226.

Jumpers 3 through 6 control the I

C address pins for the INA226. These jumpers can set the address for

A0 and A1 to either supply, ground, SCL, or SDA. Make sure to only connect one jumper at a time for

each address control. Failure to properly connect jumpers can cause shorts or interruptions in the

communication lines. For more information on the INA226 addressing, refer to the INA226 product data

sheet.
