GM393

www.DataSheet4U.com MICROELECTRONICS A A Signal Conditioning GM393 LOW POWER DUAL DIFFERENTIAL COMPARATOR Description The GM393 consist 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, square wave and time delay generators; wide range VCO; MOS clock timers; multivibrators and high voltage digital logic gates. The GM393 are designed to directly interface with TTL and CMOS. When operated from both plus and minus power supplies, the GM393 will directly interface with MOS logic, where their low power drain is a distinct advantage over standard comparators. The GM393 is available in DIP-8 and SOP-8 packages.
