I'm getting 5v.

Isn't slew rate the maximum voltage change possible per second(or here us).

So the maximum change in voltage the sin wave can have is 5v/us.

if i differentiate the sin wave( A*sin(10^6*t) ):

I get A*10^6cos(10^6*t)

The maximum change in voltage is when cos()=1.

Thus,

A*10^6

5/2pi

formula is

SR = 2 * pi * f * Vo

Idiot answer is 5/2pi

how the maximum output voltage is calculated
