1 Abstract

This user’s guide describes the characteristics, operation, and use of the INA232, INA234 and INA236 evaluation modules (EVMs). These EVMs are designed to evaluate the performance of the INA232, INA234 and INA236. Throughout this document, the terms evaluation board, evaluation module, and EVM are synonymous with the INA232EVM, INA234EVM and INA236EVM. This document includes a schematic, reference printed circuit board (PCB) layouts, and a complete bill of materials (BOM).
