I have a simple question.
I think an offset voltage drift of OP-amps has positive or negative tenpareture coefficiency, but that is not written in data sheets such as OP1117, AD829, and AD8099.
On the other hand, a sign of +/- is written in ADA4945's data sheet.
I want to know a definition of an offset voltage drift in Analog Devices. Absolute value? Standard deviation?
Or is that only positive tenpareture coefficiency?
