I'm doing a question in my text and I think the answer in the back of the book is wrong.
The task is to find the largest input voltage without creating distortion(clipping)
There is an op-amp circuit where the input is on the non-inverting input and +15V and -15V on the repective rails.
Ri= 680ohm
Rf=4.7Kohm
R(load)=10Kohm
Limits- Isc=25mA GBW=1Mhz, Slew Rate= 0.5v/uSec
When I calculate I get these answers... Gain =Rf/Ri+1 =7.91
since Isc and the slew rate limits are well below the limits of 28v by the rails I use them as my limit.
therefor I calculate the limit by the rails by dividing the rails max -2 dividing by the gain
so 28vp-p/7.91=3.54Vmax.
But for some reason the book says the answer is 4vp-p.
any help or confirmation of my answer is appreciated.
