INA241EVM

ABSTRACT

This user’s guide describes the characteristics, operation, and use of the INA241EVM evaluation module (EVM).
This EVM is designed to evaluate the performance of the INA241A or INA241B 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 INA241EVM. This document also includes a schematic, reference printed
circuit board (PCB) layouts, and a complete bill of materials (BOM).
