INA191EVM

This user’s guide describes the characteristics, operation, and use of the INA191 evaluation module
(EVM). This EVM is designed to evaluate the performance of the INA191 voltage-output, current shunt
monitor in a variety of configurations. Throughout this document, the terms evaluation board, evaluation
module, and EVM are synonymous with the INA191EVM. This document also includes a schematic,
reference printed-circuit board (PCB) layouts, and a complete bill of materials (BOM).
