This document covers all pertinent areas involved to properly use this EVM board. Throughout this document, the terms evaluation board, evaluation module, and EVM are synonymous with the INA219EVM. This document includes the physical printed circuit board layout, schematic diagrams, and circuit descriptions. -
Page 2: Overview
Overview www.ti.com 1 Overview This document provides the information needed to set up and operate the INA219EVM evaluation module, a test platform for the INA219, a high-side measurement, bidirectional current/power monitor with I C interface. For a more detailed description of the INA219, see also the product data sheet (SBOS448) available from the Texas Instruments website at http://www.ti.com. -
Page 3: Related Documentation From Texas Instruments
The following document provides information regarding Texas Instruments integrated circuits used in the assembly of the INA219EVM. This user's guide is available from the TI website under literature number SBOU074. Any letter appended to the literature number corresponds to the document revision that is current at the time of the writing of this document. -
Page 4: System Setup
2 System Setup Figure 2-1 shows the system setup for the INA219EVM. 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 INA219_Test_Board. Users can connect the INA219_Test_Board to the system and monitor the power, current, and voltage of the system under test conditions. - Page 5 A0 and A1. Connector T4 allows the connection of the shunt and bus voltages. Figure 2-3.

2.3 Theory of Operation For SM-USB-DIG Platform Figure 2-4 shows the block diagram for the SM-USB-DIG Platform. This platform is a general-purpose data acquisition system used on other Texas Instruments evaluation modules. The details of the USB DIG Platform operation are included in a separate document (available for download at www.ti.com). -
Page 8: Ina219Evm (Rev A) Hardware Setup
3 INA219EVM (Rev A) Hardware Setup The INA219EVM (Rev A) hardware setup involves connecting the three PCBs of the EVM together, applying power, connecting the USB cable, and setting the jumpers. This section details this procedure. 3.1 Electrostatic Discharge Warning Many of the components on the INA219EVM are susceptible to damage by electrostatic discharge (ESD). -
Page 9: Connecting The Hardware
INA219EVM (Rev A) Hardware Setup 3.3 Connecting the Hardware To connect the three PCBs of the INA219EVM together, gently push on both sides of the D-SUB connectors (as Figure 3-1 shows). Ensure the two connectors are completely pushed together; loose connections may cause intermittent operation. -
Page 10: Ina219 Jumper Settings
3.5 INA219 Jumper Settings Figure 3-3 shows the default jumpers configuration for the INA219EVM. Generally, the jumper settings of the SM-USB-DIG Platform will not need to be changed, but you may want to change some of the jumpers on the INA219_Test_Board to match your specific configuration. For instance, you may wish to set a specific I address. -
