PRODUCT OVERVIEW
Selection starts with the operating requirement.
SAG21 targets high-dynamic absolute feedback applications. The 25 nm technical format appears in source data, but orderability remains under review and is not presented as a standard option.
Open technical item25 nm orderability and ordering code require manufacturer confirmation.
