Topic: Analog Circuits
A sinusoidal input which can be reproduced in an OP-AMP without any distortion having slew rate of $10\pi~V/\mu s$ and 5V peak output amplitude, has the maximum frequency of
- A. 1 kHz
- B. 1 MHz
- C. 31.42 kHz
- D. 31.42 MHz
Answer: B. 1 MHz
Explanation: The maximum frequency avoiding slew rate distortion is given by $f_{m} = \frac{SR}{2\pi A_m}$. Given $SR = 10\pi~V/\mu s = 10\pi \times 10^6$ V/s, and $A_m = 5$ V. Thus, $f_{m} = \frac{10\pi \times 10^6}{2\pi \times 5} = 10^6$ Hz = 1 MHz.
