REF4132-Q1: Suggestion for voltage reference divide

Part Number: REF4132-Q1
Other Parts Discussed in Thread: OPA735

I have REF4132-25 presently.

My object is very strange reference voltage... 0.6V.

I'd like to divide voltage form REF4132-25, using resistors and OPA735, like this picture.

I set R1 to19K and R2 to 6K, I could get  0.6V output Vo.

I know that is very ideal.

But I don't see a ready-made 0.6V reference, so I divided it from the reference voltage ref4132-25.

Does anyone have any suggestion for my idea?

  • Hi DeWei

    TI doesn't offer reference below 1.024V. So you have to do voltage division. 

    You can also look into our latest release REF35120 which offers 1.2V and you can use same resistor for voltage divider. 

    Can you please explain more detail about your application. What is the level of accuracy you are looking for? We can suggest you best reference based on that..
