This user's guide describes the characteristics, operation, and use of the INA381 evaluation module
(EVM). This EVM is designed to evaluate the performance of the
INA381A4
voltage output current-shunt monitors in a variety of configurations. The EVM also provides an
internal comparator with each of the above devices, and allows the user to define reference voltages for
each device's alert function. Throughout this document, the terms evaluation board, evaluation module,
and EVM are synonymous with the INA381EVM. This document includes a schematic, reference printed-
circuit board (PCB) layouts, and a complete bill of materials (BOM).
