An op-amp has slew rate 0.5 V/microsecond. For a sine-wave output with peak amplitude 5 V, the maximum frequency before slew-rate limiting is approximately?

  • A1.59 kHz
  • B15.9 kHz
  • C159 kHz
  • D1.59 MHz
Report an error
Correct Answer: B. 15.9 kHz
Explanation: For a sine wave, SR = 2πfVp. Thus fmax = 0.5×10^6/(2π×5) ≈ 15.9 kHz.
