Product Summary
The LM2903MX is a Low Power Low Offset Voltage Dual Comparator. The LM2903MX consists of two independent precision voltage comparators with an offset voltage specification aslow as 2.0 mV max for two comparators which were de-signed specifically to operate from a single power supplyover a wide range of voltages. Operation from split powersupplies is also possible and the low power supply current drain is independent of the magnitude of the power supplyvoltage. The comparator also has a unique characteris-tic in that the input common-mode voltage range includesground, even though operated from a single power supply voltage. The applications of the LM2903MX include High precision comparators, Reduced VOS drift over temperature, Eliminates need for dual supplies, Allows sensing near ground, Compatible with all forms of logic, Power drain suitable for battery operation.
