NTE911

NTE911 Integrated Circuit Dual Voltage Comparator Description: The NTE911 is a dual, differential voltage comparator in a 10−Lead Metal Can type package featuring high accuracy, fast response times, large input voltage range, low power consumption and compatibility with practically all integreated logic forms. When used as a sense amplifier, the threshold voltage can be adjusted over a wide range, almost independent of the integrated circuit characteristics. Independent strobing of each comparator channel is provided, and pulse stretching on the output is easily accomplished. Other applications of the dual comparator include a window discriminator in pulse height detectors and a double−ended limit detector for automatic Go/No−Go test equipment.
