INA230EVM (Rev A) ABSTRACT This user's guide describes the characteristics, operation, and use of the INA230EVM evaluation board (Rev A) hardware. This document discusses how to set up and configure the software and hardware, and reviews the program operation. Throughout this document, the terms evaluation board, evaluation module, and EVM are synonymous with the INA230EVM.

INA230 under various signal, shunt, and supply conditions. This document gives a general overview of the INA230EVM and provides a general description of the features and functions to consider when using this evaluation module.
Page 3: Related Documentation From Texas Instruments
The following documents provide information regarding Texas Instruments' integrated circuits used in the assembly of the INA230EVM. This user's guide is available from the TI website under literature number SBOU124. Any letter appended to the literature number corresponds to the document revision that is current at the time of the writing of this document.

SM-USB-DIG Platform. The SM-USB-DIG Platform generates the analog and digital signals used to communicate with the INA230 test board. Users can connect the INA230EVM test board to the system and monitor the power, current, and voltage of the system under test conditions.
Page 5: Signal Definitions Of H1 (10-Pin Connector Socket)
2.2 Signal Definitions of H1 (10-Pin Connector Socket) Table 2-1 lists the pinout for the 10-pin connector socket used to communicate between the INA230EVM and the SM-USB-DIG. Note that the INA230EVM only uses the necessary I C communication lines (pins 1 and 3) and the V and GND pins (pin 6 and pin 8) to issue commands to the INA230 chip.

3.2 Connecting the Hardware To set up the INA230EVM and connect the two PCBs of the EVM together (that is, the INA230 Test Board and SM-USB-DIG Platform board), gently slide the plug and socket ends of the 10-pin connectors together.
Page 7: Connecting Power
Note It is always necessary to connect the power to the SM-USB-DIG Platform board before connecting the USB cable. Figure 3-1. Typical Hardware Test Connections for the INA230EVM SBOU124A – MARCH 2012 – REVISED MARCH 2023 INA230EVM (Rev A) Submit Document Feedback...

INA230EVM (Rev A) Hardware Setup www.ti.com 3.4 Connecting the USB Cable to the SM-USB-DIG Platform After power is connected, the computer typically responds with a Found New Hardware, USB Device pop-up dialog. The pop-up window typically changes to Found New Hardware, USB Human Interface Device. This pop-up indicates that the device is ready for use.
Page 9: Ina230Evm Default Jumper Settings
Figure 3-4. INA230EVM Default Jumper Settings Typically, jumper 2 on the INA230EVM is always set to the INT position. When set to the INT position, the SM-USB-DIG Platform provides the supply for the INA230. When this jumper is set to the EXT position, an external supply voltage can be connected to terminal strip T2 to provide the supply for the INA230.

SM-USB-DIG and the terminal block T1. If the user wants to add external signals separate from the SM-USB-DIG, simply disconnect the SM-USB-DIG from the INA230EVM board and hook up the necessary SDA, SCL, and GND lines. Also, remember to apply an external supply to the lines that is compatible with the I communication device being used.
Page 11 3.6.5 VIN+ and VIN– Input Filter (R1, R2, and C1) The INA230EVM has an optional input filter to remove high-frequency noise from the inputs VIN+ and VIN–. This filter is typically unpopulated. The default values for R1 and R2 are 0 Ω.

INA230EVM Software Overview 5 INA230EVM Software Overview This section discusses how to use the INA230EVM software. Software operation involves a two-step process: configuration of the INA230 settings and operation of the tool. 5.1 Starting the INA230EVM Software Users can operate the INA230 software through the Windows Start menu. From Start, select All Programs; then select the INA230EVM program.

Page 17 Figure 5-3. Setting the A1 Address 5.2.2 Configure Operating Mode The second step of the INA230EVM configuration process allows the user to set the operating mode and the averaging mode. The operating mode allows the user to restrict the amount of calculations done within the INA230 by changing the conversion to be triggered or continuous, or by shutting down the part altogether.
Page 18 Setting the conversion times allows the user to customize the amount of measurement time for conversions. Typically, for the INA230EVM software, the user is not able to notice a visual difference between the conversion times unless a high averaging mode and conversion time are chosen.
