LTC1151 output current (use as CCS)

I’m designing an adjustable CCS with LT1634-1,25 for Vref and LTC1151 for U/I-conversion.
I choose this opamp because I want a low drift and a high compliance voltage for the CCS (36V single supply).
Output current is from 100nA to 1mA.
The output current is not specified in the datasheet (only short circuit current, what is not relevant here).

Question: is it save to use this opamp in this output current range or would it be better to put a JFET behind it to unload the output?
Or are there other opamps better suited for this task?

Thanks, Boris
