1.1 Introduction

This user’s guide describes the characteristics, operation, and use of the INA790 and INA791 evaluation module (EVM). This EVM is designed to evaluate the performance of the current-sense amplifiers in a variety of configurations. Throughout this document, the terms evaluation board, evaluation module, and EVM are synonymous with the INA79xEVM. This document includes a schematic, reference printed circuit board (PCB) layouts, and a complete bill of materials (BOM).

See the corresponding product data sheet for comprehensive information about the INA790 and INA791.

Note: This EVM comes with either of four devices (INA790A/B and INA791A/B) populated. To evaluate, order the correct EVM from corresponding product folder.
