INTEGRATED CIRCUITS LM193A/293/A/393/A/2903 Low power dual voltage comparator Product data Supersedes data of 2002 Jan 22 2002 Jul 12 Philips Semiconductors Philips Semiconductors Low power dual voltage comparator Product data LM193A/293/A/393/A/2903 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.
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.
