LM193/LM293/LM393/LM2903 Low Power Low Offset Voltage Dual Comparators
August 2002
LM193/LM293/LM393/LM2903 Low Power Low Offset Voltage Dual Comparators
General Description
The LM193 series consists of two independent precision voltage comparators with an offset voltage specification as low as 2.0 mV max for two comparators which were designed specifically to operate from a single power supply over a wide range of voltages. Operation from split power supplies is also possible and the low power supply current drain is independent of the magnitude of the power supply voltage. These comparators also have a unique characteristic in that the input common-mode voltage range includes ground, even though operated from a single power supply voltage. Application areas include limit comparators, simple analog to digital converters; pulse, squarewave and time delay generators; wide range VCO; MOS clock timers; multivibrators and high voltage digital logic gates. The LM193 series was designed to directly interface with TTL and CMOS. When operated from both plus and minus power supplies, the LM193 series will directly interface with MOS logic where their low power drain is a distinct advantage over standard comparators. The LM393 and LM2903 parts are available in National's innovative thin micro SMD package with 8 (12 mil) large bumps.
