HI
i have an opamp (opa211) setted up in non inverting configuration with R2(feedback) resistor value as 100k and R1 as 1K. I need a gain of around 100.
Applying a signal to the input of the Amp i am not able to get an amplified signal at the output.The output i am getting is little bit amplified version of the input.Apparently i have rechecked the connections, i don't see any loose wire or bad connection.i am not sure what the problem could be.
I have attached the pin configuration Diagram for OPa211.
Here is the details of the input i Applied to the Amp.
V+=10V
V-=-10V
In+=sine wave 500mV p-p
In- =grounded
please comment
Thanks

 

Are you able to post a well focused photo of your breadboard layout?

 

hi Eng,
I make that a gain of 101, so a 0.5Vppk would require an output swing of ~50 Vppk !!!

E
EDIT:
Whats the Vin frequency?

 

V+=10V
V-=-10V
In+=sine wave 500mV p-p
In- =grounded

You can't get more than 20X gain without clipping the sine wave.

 

Double check all your connections and component values.
Do you have the power supply's common point connected to ground?
Post a compete circuit diagram.

 

Thank you all i figured it out actually the op amp was damaged i replaced it with a new one and now i can get an amplified version of the input signal.
This is such a nice knowledge sharing platform.i thank all the contributors for making it a very nice learning platform.
