Question

Quizplus · Accepted Answer

The ideal operational amplifier (op-amp) is characterized by infinite input impedance (to draw no current), zero output impedance (to supply as much current as needed), infinite voltage gain (to amplify any input signal without limitation), and infinite bandwidth (to accurately amplify signals of any frequency). Both A and C describe these ideal characteristics.
