Andy recommends favorite resources for basic op amp circuits and includes a portion of TI's AN-20. Test your knowledge with ...

In a balanced op-amp circuit, the op-amp inputs see equal impedances looking into the circuit. Balanced circuits provide better performance by cancelling some input errors and have a simple R F /R ...

What is circuit grounding? Engineers use the word “ground” in every electronic circuit to denote some part of a system or structure that is “ neutral,” or zero potential. Unfortunately, we often think ...
