LM2903 Low-Power Dual Voltage Comparator

STMicroelectronics LM2903 Low-Power Dual Voltage Comparator consists of two independent low-power voltage comparators designed to operate from a single supply over a wide range of voltages. Operation from split power supplies is also possible. The STMicroelectronics LM2903 also has a unique characteristic: the input common-mode voltage range includes the negative rail, even though it is operated from a single power supply voltage.
