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 (Vo max). Consider the use of an op amp with ftt = 2 MHz, SR = 1 V/ s, and V0 max = 10 V in the design of a non-inverting amplifier with a nominal gain of 10. Assume a sine-wave input with peak amplitude Vi. If Vi = 0.5 V, what is the maximum frequency before the output distorts?

A. 31.8 kHz
B. 318 kHz
C. 3.18 kHz
D. 3.18 MHz
Answer» B. 318 kHz
