SBOU074C – January 2009 – Revised September 2017 Submit Documentation Feedback Copyright © 2009–2017, Texas Instruments Incorporated INA219 Evaluation Module 11 INA219EVM Hardware Setup 3.6 www.ti.com Connecting External Power to the INA219EVM The INA219 power supply (VS) operates over the range of 3V to 5.5V (see the INA219 product data sheet). The default jumper position provides 5V to the INA219 from the SM-USB-DIG Platform. The power from the SM-USB-DIG Platform can be changed to 3V using JUMP9. Another option is to connect power to the INA219 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 position. The INA219 power supply (VS) operates over the range of 3V to 5.5V, so be careful to not exceed this range. 3.7 Connecting External Signals to the INA219EVM The INA219 shunt and bus voltages are applied via terminal block T4. The T4 terminal block is a direct connection to VIN+ and VIN– of the INA219. The bus voltage is monitored on VIN– (26V max). The shunt voltage is the difference between VIN– and VIN+ (320mV max). Refer to the INA219 data sheet for more details 4 INA219 Software Overview This section discusses how to install and use the INA219 software. 4.1 Operating Systems for INA219 Software The INA219EVM software has been tested on the Microsoft Windows XP operating system (OS) with United States and European regional settings. The software should also function on other Windows operating systems. 12 INA219 Evaluation Module SBOU074C – January 2009 – Revised September 2017 Submit Documentation Feedback Copyright © 2009–2017, Texas Instruments Incorporated INA219 Software Overview www.ti.com 4.2 INA219EVM Software Install Follow these steps to install the INA219EVM software: Step 1. Software can be downloaded from the INA219EVM web page, or from the disk included with the INA219EVM, which contains a folder called Install_software/. Step 2. Find the file called setup.exe. Double-click the file to start the installation process. Step 3. Follow the on-screen prompts to install the software. Step 4. To remove the application, use the Windows Control Panel utility, Add/Remove Software. 4.3 Starting the INA219EVM Software The INA219 software can be operated through the Windows Start menu. From Start, select All Programs; then select the INA219EVM program. Figure 9 shows how the software should appear if the EVM is functioning properly. When started, the software may produce an error about "Invalid calibration information" as shown in Figure 10. Dismiss this error and continue, it no longer affects current hardware. Figure 9.

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. 4.4.1 Overview Tab This tab has the following controls: • Turn the power supply on and off • Set the I2C address 4.4.2 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 INA219 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. 4.4.3 Calibrate Tab The calibration tab allows users to enter some information regarding the INA219 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 INA219 data sheet. 4.4.4 Scaling Tab This tab allows you to see how the mathematical operations work in the INA219. Specifically, this tab shows how the current and power values are computed using the full-scale calibration register. 4.4.5 Graph Tab The graph tab will display bus voltage, shunt current, and power versus time when the software is in continuous convert mode. 4.4.6 Registers Tab This tab allows you to read and edit all the registers in the INA219. 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. 16 INA219 Evaluation Module SBOU074C – January 2009 – Revised September 2017 Submit Documentation Feedback Copyright © 2009–2017, Texas Instruments Incorporated INA219 Software Overview www.ti.com 4.4.7 EVM Controls Pull-Down Menu The INA219 Configuration (that is, the register settings) can be saved or loaded using the EVM Controls drop-down menu, as Figure 13 shows.
