The slew rate of an operational amplifier is 0.5 V/micro

Home » Analog Electronic Circuits » Analog electronics circuits miscellaneous » Question

The slew rate of an operational amplifier is 0.5 V/micro sec. The maximum frequency of a sinusoidal input of 2 V_rms that can be handled without excessive distortion is:

1. 3 kHz
2. 30 kHz
3. 300 kHz
4. 2 MHz

Correct Option: B

f_max =	Slew rate
	2π·V_m

=	0·5 × 10⁶	V_rms = 2 =	V_m
	2 × π × 2 √2		√2

⇒ V_m = 2√2 = 28 kHz
Hence alternative (B) is the most closet answer.
