ADR510 reverse characteristics?

I don't see anything in the data sheet about the reverse characteristics of the ADR510 1.0 V reference.  Is there a protection diode between anode & cathode that becomes forward biased when the ADR510 is reverse biased?  I would like to use two ADR510s in inverse parallel to make a precision +/- 1 V clamp, but that wouldn't work with a protection diode in there.

Thanks,

Gerrit

  • Hello Mon, 

    Sorry, I didn't see that you'd replied to this until now. 

    I didn't explain that very well, you're right that the reference is normally reverse biased so I meant forward biased.  I want to use two ADR510's back to back like this:

    to form a +/- 1 V clamp.  The forward biased reference would need to not have a forward biased protection diode (about 600 mV) for this to work.

    Thanks,
