    Overview The INA223 is a voltage output device that monitors current, bus voltage, and power of a supply line by sensing a voltage drop across a shunt. The INA223EVM is a platform for evaluating the performance of the INA223 under various signal, shunt, and supply conditions. This document gives a general overview of the INA223EVM, and provides a general description of the features and functions to be considered while using this evaluation module.

    SCL, or SDA. Make sure to connect only one jumper at a time for the address control (for example, if JMP1 is connected, do not connect JMP2, and vice versa). Failure to properly connect jumpers can cause shorts or interruptions in the communication lines. For more information on the INA223 addressing, consult the INA223 data sheet (SBOS528).
  • Page 10 SM-USB-DIG Platform and terminal block T3. If external signals separate from the SM-USB- DIG are to be used, simply disconnect the SM-USB-DIG from the INA223 board and connect to external SDA, SCL, and GND lines. Also, remember to apply an external V that is compatible with the I communication device being used.
