HA17903, HA17393 Series Dual Comparator Description HA17903 and HA17393 are comparators designed for car use and control system use. They provide wide voltage range with single power source, and the change of supply current is small, because it is independent of the supply voltage. They can be widely applied, such as limit comparator, simple analog/digital converter, pulse/square wave/time delay generator, wide range VCO, MOS clock timer, multivibrator, high voltage logic gate, etc. Features • • • • • • • Wide supply voltage: 2 to 36V Very low supply current: 0.8mA Small input bias: 25nA Small input offset current: 3nA Small input offset voltage: 2mV Common mode input voltage range including ground. Small output saturation voltage: 1mV (5µA) 70mV (1mA) • Output voltage i [ ... ]
