Theory of Operation For USB_DIG_Platform
Figure 5 shows the block diagram for the USB DIG Platform. This platform is a general-purpose data
acquisition system that is used on several different Texas Instruments evaluation modules. The details of
its operation are included in a separate document (available for download at www.ti.com). The block
diagram shown in Figure 5 gives a brief overview of the platform. The primary control device on the USB
DIG Platform is the TUSB3210.

Figure 5. USB_DIG_Platform Theory of Operation
An important function of the USB DIG is to power the EVM PCB. As depicted in Figure 5, switched power
for the EVM can be derived from the PC's USB supply or alternatively from an external power source
connected to J5. TI recommends using the external supply option because the USB power supply can be
noisy. The barrel connector cable assembly included in the EVM kit can be used to connect an external
power supply to the USB DIG. Connect the black wire of the cable assembly to the low side (or ground) of
the external supply and the red wire to the high side.
NOTE: For proper operation, the external source must provide a supply voltage between 5.8 V and
10.4 V and have a current limit greater than 100 mA

INA220EVM Hardware Setup
The INA220EVM hardware setup involves connecting the two PCBs of the EVM together, applying power,
connecting the USB cable, and setting the jumpers. This section presents the details of this procedure.
3.1
Electrostatic Discharge Warning
Many of the components on the INA220EVM are susceptible to damage by electrostatic discharge (ESD).
Customers are advised to observe proper ESD handling precautions when unpacking and handling the
EVM, including the use of a grounded wrist strap at an approved ESD workstation.
CAUTION
Failure to observe ESD handling procedures may result in damage to EVM
components.
3.2
Typical Hardware Connections
The INA220EVM hardware setup involves connecting the two PCBs of the EVM together, applying power,
and connecting an external shunt and load. The external connections may be the real-world system that
the INA220 will be incorporated into. Figure 6 shows the typical hardware connections.

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 7). Make sure that the two connectors are completely pushed together; loose
connections may cause intermittent operation.
3.4
Connecting Power
After the two parts of the INA220 EVM are connected, as Figure 7 illustrates, connect the power to the
EVM. Always connect power before connecting the USB cable. If you connect the USB cable before
connecting the power, the computer will attempt to communicate with an unpowered device that will not be
able to respond.

Connecting the USB Cable to the INA220EVM
Figure 8 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. The pop-up typically changes to Found
New Hardware, USB Human Interface Device. This pop-up indicates that the device is ready to be used.
The USB DIG platform uses the Human Interface Device Drivers that are part of the Microsoft® Windows®
operating system.
In some cases, the Windows Add Hardware Wizard will pop up. If this prompt occurs, allow the system
device manager to install the Human Interface Drivers by clicking Yes when requested to install drivers.

INA220 Jumper Settings
Figure 9 shows the default jumpers configuration for the INA220EVM. In general, the jumper settings of
the USB DIG Platform will not need to be changed. You may want to change some of the jumpers on the
INA220_Test_Board to match your specific configuration. For instance, you may wish to set a specific I2C
address.

Table 3 summarizes the function of the USB DIG platform jumpers. For most applications, the default
jumper position should be used. Table 4 and Table 5 describe the options for the power-supply
configuration. For example, the logic power supply can be changed from the default of 5V to 3V. A
separate document (SBOU058) gives details regarding the operation and design of the USB DIG platform.

Connecting External Power to the INA220EVM
The INA220 power supply (VS) operates over the range of 3V to 5.5V (see the INA220 product data
sheet). The default jumper position provides 5V to the INA220 from the USB-DIG-Platform. The power
from the USB-DIG-Platform can be changed to 3V using JUMP9.
Another option is to connect power to the INA220 power supply (VS) using an external power supply. In
this case, connect power to the T3 terminal block and set JMP1 to the Vs_EXT positon. The INA220
power supply (VS) operates over the range of 3V to 5.5V, so be careful to not exceed this range.
3.8
Connecting External Signals to the INA220EVM
The INA220 shunt and bus voltages are applied via terminal block T4. The T4 terminal block is a direct
connection to VIN+ and VIN– of the INA220. The bus voltage is monitored on VBUS (26V max). The shunt
voltage is the difference between VIN– and VIN+ (320mV max). Refer to the INA220 data sheet for more
details

Figure 11 shows an error that pops up if the computer cannot communicate with the EVM. If you receive
this error, first check to see that the USB cable is properly connected. This error can also occur if you
connect the USB cable before the USB DIG Platform 9V power source. A second possible reason for this
problem is that there may be a problem with your computer USB Human Interface Device Driver. Make
sure that when you plug the in the USB cable, the computer recognizes the device. If the sound is on, you
will hear the distinctive sound that you expect when a USB device is properly connected to the PC.

INA220 Software Overview
4.3
www.ti.com
Using the INA220 Software
The INA220EVM software has six different tabs that allow you to access different features of the INA220.
The first four tabs are designed so that you can completely configure the device by stepping through the
tabs in order. Each of the tabs is intended to have an intuitive graphical interface that helps you gain a
better understanding of the device.
4.3.1
Overview Tab
This tab has the following controls:
• Turn the power supply on and off
• Set the I2C address
4.3.2
Config Tab
This tab has the following controls:
• Shunt voltage attenuator range (smallest range: 40mV; largest range: 320mV)
• Shunt voltage configuration: resolution and number of averages. Note that increasing the number of
averages decreases the noise but slows down the conversion rate.
• Bus voltage attenuator range (16V and 32V): Note that the maximum bus voltage for the INA220 is
26V. Thus, the 32V range cannot be fully used.
• Bus voltage configuration: Resolution and number of averages. Note that increasing the number of
averages decreases noise but slows down the conversion rate.
• A/D converter mode: This control determines how the converters work. The most commonly used
modes are Shunt and Bus continuous conversion mode. This mode causes both converters to run
continuously.
More details on these options are explained in the product data sheet.
4.3.3
Calibrate Tab
The calibration tab allows users to enter some information regarding the INA220 configuration in a given
application. This information is used to compute the Full-Scale Cal Register. The Full-Scale Cal Register
converts the shunt voltage to a current value. The detailed mathematics behind this calibration feature is
given in the INA220 data sheet. Also, this feature is explained in a step-by-step manner in the video.
4.3.4
Scaling Tab
This tab allows you to see how the mathematical operations work in the INA220. Specifically, this tab
shows how the current and power values are computed using the full-scale calibration register.
4.3.5
Graph Tab
The graph tab will display bus voltage, shunt current, and power versus time when the software is in
continuous convert mode.
4.3.6
Registers Tab
This tab allows you to read and edit all the registers in the INA220. All the previous tabs affect the register
listing. For example, changing the A/D configuration on Tab 2 will affect Register 0 in the register list. It is
also true that changing register 0 updates the A/D configuration on Tab 2. Thus, the graphical
representation and register representation affect each other.
