Operational Amplifier-Basic Concepts and Applications

WebAt lower frequencies, the phase shift is smaller, so no problems arise. At frequencies between f1 and f2, the magnitude of the open-loop gain falls, and the phase remains at −90°, so the amplifier is still stable. At f2 and above, the phase of the open-loop gain approaches −180°, making the loop gain positive. Webdepended on Bias Current. The op-amp provides a gain of 63dB and a bandwidth of 140 kHz for a load of 1 pF. This op-amp has a Common Mode gain of -25 dB, an output slew rate of 32 V= s, and a output voltage swing.
