bandwidth
An ideal op-amp is a voltage amplifier with infinite input impedance, zero output impedance, and infinite bandwidth. In the real world, however, these parameters are limited by small imperfections in semiconductor manufacturing, effects of temperature, and so on.
Understating Bandwidth Limitations in Operational-Amplifiers
Op-amps are the mainstay of analog electronics. You can find them performing a wide range of functions such as amplification, filtering, comparing, and performing mathematical operations among others.
