PRODUCT DESCRIPTION

The AD790 is a fast (45 ns), precise voltage comparator, with a number of features that make it exceptionally versatile and easy to use. The AD790 may operate from either a single 5 V supply or a dual ±15 V supply. In the single-supply mode, the AD790’s inputs may be referred to ground, a feature not found in other comparators. In the dual-supply mode it has the unique ability of handling a maximum differential voltage of 15 V across its in put terminals, easing their interfacing to large amplitude and dynamic signals.
