I have some questions about ADR504x.
For example,this is from ADR5040 datasheet.
Does this mean if Iin's value goes higher , the output voltage will goes higher?
I think this means that ADR504x has parasitism resistance.
So if Iin goes higher , it looks like the output voltage goes higher.
Is my understanding correct?
I simulate this at ADIsimPE.
There is no minimum value for Output voltage change .
Does this mean minimum value is 0mV?
Also , for example , 1.75mV is +1.75mV.
Is this correct?
At the datasheet, it says that Iin_max is 60uA.
But at "Output voltage change" it says Iin is 50uA_min at all temp.
Is this typo?
Iin = 60uA to 1mA is correct?
Can anybody help about this?
I just contacted our product expert regarding your query. I will get back to you soon.
Thank you for your support.
I understood what you said.
This is a shunt reference, so you have to think a little differently.
See figure 4 in MT-087
To power all of the transistors, takes a MINIMUM of 60uA over temperature.
That is what that line means.
As you try to put more current into the part, Q9 in figure 4 turns on harder.
But transistors are not perfect and have a Vce(sat) that is a function of current.
So Q9 tries to sink all the extra current, but it can't, so the voltage across it rises.
This is why you see the graph in SimPE that you see.
So with a shunt reference, the change is always positive. (zero to 1.75mV)
