An amplifier's slew rate is \( 1 \ \mathrm{V/\mu s} \). The largest undistorted \( 10 \ \mathrm{V} \) peak sine wave it can produce is at about
Answer: A
The steepest slope of a sine wave is at its zero crossing:
\[ \begin{aligned} 2\pi f A &\le 10^{6} \\ f &\le \tfrac{10^{6}}{2\pi \times 10} \approx 16 \ \mathrm{kHz} \end{aligned} \]
giving about 16 kHz. Above that the output becomes a triangle rather than a sine, however wide the small-signal bandwidth. The limit falls in proportion to amplitude, so the same amplifier reaches ten times the frequency at a tenth of the output.
