Description for the LM393-N

The LM193-N series consists of two independent precision voltage comparators with anoffset voltage specification as low as 2.0 mV max for two comparators which were designedspecifically to operate from a single power supply over a wide range of voltages. Operation fromsplit power supplies is also possible and the low power supply current drain is independent of themagnitude of the power supply voltage. These comparators also have a unique characteristic in thatthe input common-mode voltage range includes ground, even though operated from a single powersupply 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 highvoltage digital logic gates. The LM193-N series was designed to directly interface with TTL andCMOS. When operated from both plus and minus power supplies, the LM19-N series will directlyinterface with MOS logic where their low power drain is a distinct advantage over standardcomparators.

The LM393 and LM2903 parts are available in TI’s innovative thin DSBGA package with 8 (12mil) large bumps.
