AN-1868 EMIRR Evaluation Boards for LMV861/LMV862 (Rev. A)
To demonstrate the EMI robustness of the LMV861/LMV862 and to be able to measure the parameter
EMIRR, two evaluation boards have been developed; one for each device. This document describes the
evaluation boards and explains how to perform EMIRR measurements. Focus is on one of the input pins
as those are most sensitive to EMI. Based on symmetry considerations, it can be expected that both
inputs have the same EMIRR. For reasons of simplicity of the required schematic the measurement on the
IN+ pin is selected. A detailed description on EMI and EMIRR for the other pins can be found in the
AN-1698 A Specification for EMI Hardened Operational Amplifiers Application Report (SNOA497).
