Part Number : LM393
Function : Low Power Low Offset Voltage Dual Comparator
Maker : National , Texas Instruments
Pinouts : 
Description :
The LM393, 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 characteris tic in that the input common-mode voltage range includes ground, even though operated from a single power supply voltage.
Features
1. Reduced VOS drift over temperature
2. Eliminates need for dual supplies
3. Allows sensing near ground
4. Compatible with all forms of logic
5. Power drain suitable for battery operation
