Analog Devices just introduced the MAT12

Just introduced.

I don't recall when they announced that part--must be a year back or more. Been available for several month.

Seems to be a respec of the same die, to increase yield.

As far as I know it's an entirely new process. They don't offer any graded parts anymore so offset and hFE mismatch is similar to that of the MAT02F. Noise seems to have improved according to my measurements.
