INA2191EVM

ABSTRACT

This user’s guide describes the characteristics, operation, and use of the INA2191 evaluation module (EVM). 
This EVM is designed to evaluate the performance of the dual-channel, bidirectional, voltage-output, INA2191 
current shunt monitor in a variety of configurations. Throughout this document, the terms evaluation board, 
evaluation module, and EVM are synonymous with the INA2191EVM. This document also includes a schematic, 
reference printed circuit board (PCB) layouts, and a complete bill of materials (BOM).
