The LMx39-N series consists of four independent precision voltage comparators with an offset voltage specification as low as 2 mV maximum for all four comparators. These comparators were designed specifically to operate from a single power supply over a wide range of voltages.

Features of LM339 Quad Differential Comparators IC:

• Input: 2 to 36 VDC or ±1 to ±18 VDC.
• Very Low Supply Current Drain (0.8 mA).
• Low Input Biasing Current: 25 nA.
• Low Input Offset Current: ±5 nA.
• Offset Voltage: ±3 mV.
• Differential Input Voltage Range Equal to the Power Supply Voltage .
• Low Output Saturation Voltage: 250 mV at 4 mA.

Applications of LM339 Quad Differential Comparators IC:

• These are used in RF communication purposes like as:
• It is used in all types of electrical/electronic projects.
• Robotics projects.
