In designing with op amps one has to check the limitations on the voltage and frequency

Chapter 2, Problem 2.127

(choose chapter or problem)

In designing with op amps one has to check the limitations on the voltage and frequency ranges of operation of the closed-loop amplifier, imposed by the op-amp finite bandwidth (ft), slew rate (SR), and output saturation (Vomax). This problem illustrates the point by considering the use of an op amp with ft = 20 MHz, SR = 10 V/s, and Vomax = 10 V in the design of a noninverting amplifier with a nominal gain of 10. Assume a sine-wave input with peak amplitude Vi . (a) If Vi = 0.5 V, what is the maximum frequency before the output distorts? (b) If f = 200 kHz, what is the maximum value of Vi before the output distorts? (c) If Vi = 50 mV, what is the useful frequency range of operation? (d) If f = 50 kHz, what is the useful input voltage range?
