Page 5: System Setup
2 System Setup Figure 2-1 shows the system setup for the INA220EVM. The PC runs software that communicates with the USB DIG Platform. The USB DIG Platform generates the analog and digital signals used to communicate with the INA220_Test_Board. Users can connect the INA220_Test_Board to the system and monitor the power, current, and voltage of the system under test conditions. - Page 6 A0 and A1. Connector T4 allows the connection of the shunt and bus voltages. Figure 2-3.

INA220EVM (Rev C) Hardware Setup 3 INA220EVM (Rev C) Hardware Setup The INA220EVM (Rev C) hardware setup involves connecting the two PCBs of the EVM together, applying power, connecting the USB cable, and setting the jumpers. This section details this procedure. -
Page 10: Connecting The Hardware
INA220EVM (Rev C) Hardware Setup www.ti.com 3.3 Connecting the Hardware To connect the two PCBs of the INA220EVM together, gently push on both sides of the D-SUB connectors (as shown in Figure 3-2). Ensure the two connectors are completely pushed together; loose connections may cause intermittent operation. -

INA220EVM (Rev C) Hardware Setup 3.5 Connecting the USB Cable to the INA220EVM Figure 3-3 shows the typical response to connecting the USB DIG platform to a PC USB port for the first time. Note that the EVM must be powered on before connecting the USB cable. Typically, the computer will respond with a Found New Hardware, USB Device pop-up. -
Page 12: Ina220 Jumper Settings
3.6 INA220 Jumper Settings Figure 3-4 shows the default jumpers configuration for the INA220EVM. In general, the jumper settings of the USB DIG Platform will not need to be changed, but you may want to change some of the jumpers on the INA220_Test_Board to match your specific configuration. - Page 13 INA220EVM (Rev C) Hardware Setup Table 3-2. USB DIG Platform Jumper Settings JUMPER DEFAULT PURPOSE JUMP1 This jumper selects external power or bus power. External power is applied on J5 (on USB DIG board) or T3 (9 V ). Bus power is 5 V from the USB.

INA220EVM (Rev C) Hardware Setup 3.7 Connecting External Power to the INA220EVM The INA220 power supply (V ) operates in the range of 3 V to 5.5 V (see the INA220 product data sheet). The default jumper position provides 5 V to the INA220 from the USB-DIG-Platform. The power from the USB-DIG-Platform can be changed to 3 V using JUMP9. -
