Analog Devices uses six designations to inform our customers where a semiconductor product is in its life cycle. From emerging innovations to products which have been in production for twenty years, we understand that insight into life cycle status is important. Device life cycles are tracked on their individual product pages on analog.com, and should always be consulted before making any design decisions.
This particular articl/edocument/design has been retired or deprecated, which means it is no longer maintained or actively updated, even though the devices themselves may be Recommended for New Designs or in Production. This page is here for historical/reference purposes only.
