Overview
The AD790JNZ, produced by Analog Devices Inc., is a fast and precise voltage comparator designed for versatility and ease of use. This device operates with either a single +5 V supply or a dual ±15 V supply, allowing its inputs to be referenced to ground in single-supply mode. The AD790JNZ is fabricated using Analog Devices' Complementary Bipolar (CB) process, which ensures a combination of fast response time (45 ns) and outstanding input voltage resolution (1 mV max). It features a 'low glitch' output stage that minimizes power supply disturbances and unwanted oscillations, making it suitable for a wide range of analog signal processing and data acquisition applications.
