Universal Instrumentation Amplifier Evaluation Module:
This user's guide describes the characteristics, operation, and use of the INAEVM-ALT-SO8, a universal
evaluation module (EVM) that is compatible with a variety of instrumentation amplifiers (INAs), specifically
those with the resistor gain pins at pins 2 and 3. This EVM is compatible with the SOIC-8 (D) package,
and is designed to evaluate the performance of the devices in both single-supply and dual-supply
configurations. This document includes the schematic, printed circuit board (PCB) layout, and BOM.
Throughout this document the terms evaluation board, evaluation module, and EVM are synonymous with
the universal INAEVM-ALT-SO8.
