AD790 is a fast (45 ns), precise voltage comparator from Analog Devices (ADI). It has 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' processes and offers high performance, low power consumption, and low noise.
The AD790 is a fast, precision comparator offered by Analog Devices. It can operate from a single 5 V supply or a dual +15 V supply and includes an onboard latch, low‑glitch output, and wide input voltage range, making it suitable for zero‑crossing detectors, over‑voltage detectors, pulse‑width modulators, and precision rectifiers.
The document lists detailed electrical specifications such as propagation delay, input offset voltage, power dissipation, and latch timing, and provides typical application circuits, ordering information, and performance graphs to aid designers in implementing the AD790 in analog signal‑processing and data‑acquisition systems.
