First, assume that the current flowing into the input of the op amp is zero. This assumption is almost completely correct for FET op amps, because the input current for FET op amps is below 1pA. But for dual high-speed op amps, this assumption is not always correct, because the input ...
It has infiniteslew rate, and therefore would swing to either rail—both equally destructive—instantly. Therefore an ideal op amp, just lying on the table with no power applied, would instantly take a quantum difference between its + and − terminals and amplify it to an infinite voltage ou...
Op amps are considered wideband fast settling if their bandwidth is greater than 5 MHz, they slew at more than 10 V/μs, and they settle to 0.1% in 1 μs or less. 2.3.2.5 Slew Rate The slew rate of an amplifier is the rate at which the output voltage can change when high drive...
