The LM339N Quad Comparator consists of four independent precision voltage comparators with an offset voltage specification as low as 2 mV max for all four comparators.
Operation from split power supplies are also possible.
Supply Voltage: +36 VDC or +/-18 VDC
Input Voltage: -0.3 VDC to +36 VDC
Input Current: 50mA
Voltage Gain: 50 to 200V/mV
Output Sink Current: 16mA
High precision comparators
Reduced Vos Drift over temperature
Eliminates need for dual supplies
Allows sensing near GND
Compatible with all forms of logic
Power drain suitable for battery operation
