OP27AZ for new design?

Q

Is the part: OP27AZ suitable for new designs, or would you suggest an
alternative part for production runs through the next 5-6 years?

A

There are no current plans to obsolete the OP27, although you might consider
newer alternative like ADA4004-1. OP27AZ is in a ceramic DIP package that is
rapidly losing favor among our customer base, and customers will likely see
price increases in the not too far future to cover for less demand on such
older packages.
