INTRODUCTION V+ WHY USE AN OP AMP AS A COMPARATOR?

WebIntroduction to Operational Amplifiers. An op amp is a voltage amplifying device. With the help of some external components, an op amp, which is an active circuit element, can … WebThe op amp represents high impedance, just as an inductor does. As C 1 charges through R 1, the voltage across R 1 falls, so the op-amp draws current from the input through R L. This continues as the capacitor charges, and eventually the op-amp has an input and output close to virtual ground because the lower end of R 1 is connected to ground.
