Overview: EMI interferes with noise sensitive analog circuitry leading to erroneous readings and misleading data. EMI is coupled or conducted and leads to hard to debug problems. A common approach is to add a filter at the input of the op amp, but this approach can cause more problems than fix them. A superior approach is to choose an EMI hardened op amp.
