NTE911 Integrated Circuit Dual Voltage Comparator Description: The NTE911 is a dual, differential voltage comparator in a 10Lead Metal Can type package featuring high accuracy, fast response times, large input voltage range, low power consumption and compatibil- ity 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. Inde- pendent 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.
