I don't know exactly but it is for supplying a rail-to-rail ampliop so it is in the mA rangeyou must write how current you need
the opamp is AD820, in the datasheet is wrote that it has a 5V to 30V single supply capability and ±2.5V to ±15V dual supply capability, does that mean that i can't supply it with ±30V??opamp part number?
Circuit schematic?

How can you make a mistake like this after being in electronics for 40 years ?????????
I need a schematic of a circuit which converts +12V dc input to -30V dc output, thank you.
Unless you are being extremely literal on the word "can't", there is not mistake here. Yes, you can supply it with ±30V, but the result will not be good."the opamp is AD820, in the datasheet is wrote that it has a 5V to 30V single supply capability and ±2.5V to ±15V dual supply capability, does that mean that i can't supply it with ±30V??"
duke37 "yes"

Both of them are fine symmetrical or single supplied the most importint for me is to get -30V.do you want output symmetrical( i mean voltage will be symmetrical from -U to +U ) , Maybe will be good single supply for this circuit. How circuit you build? you can use single supply , and later use capacitor to filter constant current.
To supply an amplifierWhy do you want -30v?
