Product Description

The LM239J is a low power low offset Voltage Quad Comparator with an offset voltage specification as low as 2mV maximum. This comparator is 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. This comparator also has unique characteristic in that the input common-mode voltage range includes ground, even though it is operated from a single power supply voltage. The LMx39-N series was designed to directly interface with TTL and CMOS. When operated from both plus and minus power supplies, the device directly interface with MOS logic - where the low power drain of the LM339 is a distinct advantage over standard comparator.
Wide supply-voltage range
Input common-mode voltage range includes ground
Differential input voltage range equal to the power supply voltage
Output voltage compatible with TTL, DTL, ECL, MOS and CMOS logic systems
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
