AD790SQ/883B

快速，精密比较器 Fast, Precision Comparator

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 input terminals, easing their interfacing to large amplitude and dynamic signals.
