INA230EVM Hardware Setup

Figure 2 shows the overall system setup for the INA230EVM. The PC runs software that communicates

with the SM-USB-DIG Platform. The SM-USB-DIG Platform generates the analog and digital signals used

to communicate with the INA230 test board. Connectors on the INA230EVM test board allow the user to

connect to the system under test conditions to monitor the power, current, and voltage.

Theory of Operation for INA230 Hardware

A block diagram of the INA230 test board hardware setup is shown in Figure 3. The PCB provides

connections to the I

board. The PCB also provides connection points for external connections of the shunt voltage, bus

voltage, and ground.
