AD790JRZ

AD790 is a fast, precise voltage comparator, with a number of features that make it exceptionally versatile and easy to use. This device may operate from either a single 5V supply or a dual ±15V supply. In the single-supply mode, the device’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 15V across its input terminals, easing their interfacing to large amplitude and dynamic signals. This device is fabricated using Analog Devices’ Complementary Bipolar (CB) process which gives the device’s combination of fast response time and outstanding input voltage resolution (1mV max). It is widely used in application such as zero-crossing detectors, overvoltage detectors, pulse-width modulators, precision rectifiers, discrete A/D converters, delta-sigma modulator A/Ds etc.
