ADL5391 offset question

Hi all,

I'm using an ADL5391 down to DC. The output offset voltage is adjusted to exactly 0 using the Z input.

Now there is still some offset as a function of temperature for which I would like to make compensation circuit.

The data sheet of th ADL5391 shows a positive temperature coefficient for the offset voltage (figure 11).

Is the slope of this graph always positive and equally steep, or does this figure just show the worst case. In other words: can I use a fixed compensation in order to counter for the temperature dependancy?

Thanks,

Paul
