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. This device is fabricated using Analog Devices.
The AD790 is a versatile voltage comparator fabricated using Analog Devices' Complementary Bipolar (CB) process. It features a maximum propagation delay of 45 ns and offers the unique ability to operate from either a single 5 V supply or dual ±15 V supplies. In single-supply mode, its inputs can be referred to ground, while in dual-supply mode, it handles a maximum differential input voltage of 15 V.
