LM2903M - Texas Instruments : Low Power Low Offset Voltage Dual Comparators
The LM2903M comprises of two independent precision voltage comparators. The following article will show the introduction of the component.
The LM2903M comprises of two independent precision voltage comparators with an offset voltage specification as low as 2.0 mV max for two comparators that were designed to operate across a wide variety of voltages from a single power source. It is also possible to operate from split power supplies, and the low power supply current drain is unaffected by the amount of the power supply voltage. Even though run from a single power supply voltage, these comparators have a unique feature in that the input common-mode voltage range includes ground.
