For an operational amplifier, the rise time and slew rat should be determined. Concept introduction: Rise time of an operational amplifier is a parameter which relates to the speed or bandwidth Δ f and it denotes the time for the output of the voltage follower to a step input to change from 10% to 90% of the total change in output. Rise time t r = 1 3 Δ f Slew rate represents the maximum rate of change of output in response to the step input. Slew rate S = Δ v Δ t r , Δ v representing change in output voltage.

Interpretation Introduction

Interpretation:

For an operational amplifier, the rise time and slew rat should be determined.

Concept introduction:

Rise time of an operational amplifier is a parameter which relates to the speed or bandwidth Δf and it denotes the time for the output of the voltage follower to a step input to change from 10% to 90% of the total change in output.

Rise time tr=13Δf

Slew rate represents the maximum rate of change of output in response to the step input.

Slew rate S=ΔvΔtr, Δv representing change in output voltage.
