3.3 Configuration of INA233EVM Jumper Settings

Figure 3-2 shows the default jumper configuration for the INA233EVM. In general, the jumper settings of the SM-USB-DIG Platform do not need to be changed. Change the jumpers on the INA233EVM board to match your specific configuration. For example, set a specific I2C address by configuring J1 and J2.

Typically, jumper 3 (J3) on the INA233EVM is always set to the INT position. When set to the INT position, the SM-USB-DIG Platform provides the supply for the INA233. When this jumper is set to the EXT position, an external supply voltage can be connected to test point VS_EXT to provide the supply for the INA233.

Jumper 1 (J1) and jumper 2 (J2) control the I2C address pins for the INA233. 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 INA233 addressing, refer to the INA233 product data sheet.

Table 3-1 summarizes the function of the INA233 Test Board jumpers. For most applications, all jumpers must be left in the respective default configurations.

Table 3-1 INA233EVM Test Board Jumper Functions
Jumper Default Purpose
J3 INT This jumper selects whether the VS pin on the INA233 is connected to the VDUT signal generated from the SM-USB-DIG Platform or whether the digital supply pin is connected to test point VS_EXT, allowing for an external supply to power the device. The default INT position connects the VS pin to the VDUT control signal.
J1 GND This jumper selects the I2C A0 address selection for A0.
J2 GND This jumper selects the I2C A1 address selection for A1.
