Opamp reference

Hi,

I am wiring opamp in differential configuration . The non inverting pin has a divider 40K by 10K referenced to GND and the signal reference of 10V is to be aplied to one end of 40K resistor. My question is should this reference of 10V(REF01) require any buffering ?

Thanks
 
Post a schematic. Also describe the reference voltage generator, and post a schematic of it if possible.
 
Here is the schematic. Does the reference IC requires a buffer?

I don't know what the IC is, but 50K is alot of resistance, so I'm going to say that a buffer is not required.

In my first post I say the number REF01 .

Thanks
