Low Power Low Offset Voltage Dual Comparators
General Description Advantages
The LM193 series consists of two independent precision n High precision comparators
voltage comparators with an offset voltage specification as n Reduced VOS drift over temperature
low as 2.0 mV max for two comparators which were de- n Eliminates need for dual supplies
signed specifically to operate from a single power supply n Allows sensing near ground
over a wide range of voltages. Operation from split power n Compatible with all forms of logic
supplies is also possible and the low power supply current
n Power drain suitable for battery operation
drain is independent of the magnitude of the power supply
voltage. These comparators also have a unique characteris-
tic in that the input common-mode voltage range includes Features
