1 Overview

This document provides the information needed to set up and operate the INA220EVM evaluation module, a test platform for the INA220, a high or low side, bidirectional current and power monitor with an I2C interface. For a more detailed description of the INA220, see also the product data sheet available from the Texas Instruments website at http://www.ti.com. Additional support documents are listed in the section of this guide entitled Related Documentation from Texas Instruments.

The INA220EVM is an evaluation module used to fully evaluate the INA220 current and power monitor device. The INA220EVM consists of two printed circuit boards (PCBs). One board (the USB DIG Platform) generates the digital signals required to communicate with the INA220, which is part of the second board (INA220_Test_Board), as well as support and configuration circuitry.

Throughout this document, the abbreviation EVM and the term evaluation module are synonymous with the INA220EVM.
