      Hi Harry-san, The source and the sink current spec have not been decided yet. Would you show me a schematic using an AD8615 as a buffer? Regards, Kazu

      Kazu-san, Some of the other refs will source 10-15 mA min, and sink 5 mA min, but I don't know of any refs that will sink/source 30 mA. Maybe an AD8615 would work as a buffer; it depends on how close you want to get to …

      Hi Harry, Thank you for supporting this case. I'll use the REF194 as a surge clamp (4.5V clamp) so I need sink current function. Do you have any device which has sink/source (both 30mA) function? If you recommend to use an op amp to buffer, please send …

      No. See figure 20 on the data sheet. The resistor divider is very high (>100k), so it will sink microamps. The REF19x family was designed to be micropower, so if you need to sink you will have to buffer with an op amp. Harry

      Hello, I could not find any current sink specifications in the REF195GSZ datasheet for the load regulation parameter. How much current REF195 can sink and what are the load regulation parameters in case of current sink? Thanking you in advance.

      … the tolerance/accuracy on the output voltage? In my Board, I am using "CURRENT-BOOSTED REFERENCES WITH CURRENT LIMITING" circuit with Vs =12V and the output that I am getting is solid 4.97V. (REF195GSZ) Could you please help to understand the output voltage behavior more in detail? Thank you
