LM339N/NOPB

The LM339N/NOPB is a low power low offset Voltage Quad Comparator with an offset voltage specification as low as 2mV maximum for all four comparators. 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.

• Very low supply current drain (0.8mA) - independent of supply voltage
• 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
• Green product and no Sb/Br
