AD790JN (AD790) Fast Precision Comparator IC
The AD790JN is a high-speed, high-precision comparator IC developed by Analog Devices, designed for accurate and fast analog signal comparison applications. It features low input offset voltage, high common-mode rejection, and fast response time, making it ideal for precision analog and digital systems.
With a typical response time of 35 ns and input offset voltage under 0.5 mV, the AD790 provides both speed and accuracy — suitable for demanding applications such as data acquisition systems, voltage level detection, and high-speed control loops.
This comparator operates from dual or single power supplies and is housed in a standard 8-pin DIP package, ensuring easy integration into both analog and mixed-signal circuits.
