This application note considers off-data-sheet operation of integrated circuits (ICs). It discusses the pitfalls awaiting engineers who have not experienced Murphy’s Law, which is anything that can go wrong, will go wrong at the worst possible time. The article reviews the thought process of an experienced and inexperienced engineer, and how they can make a circuit immune to leakage from environmental contamination, radio frequency interference, and electro static discharge.
The article provides explanations on how to avoid pitfalls common to inexperienced engineers when designing from data sheets. From knowing what various data sheet specifications actually mean to learning how to protect your ICs from electrostatic discharge and RF interference is covered in this app note.
