1 Features 3 Description

The LMx39-N series consists of four independent

1• Wide Supply Voltage Range

precision voltage comparators with an offset voltage

• LM139/139A Series 2 to 36 VDC or ±1 to ±18 VDC specification as low as 2 mV maximum for all four

• LM2901-N: 2 to 36 VDC or ±1 to ±18 VDC comparators. These comparators were designed

• LM3302-N: 2 to 28 V specifically to operate from a single power supply DC or ±1 to ±14 VDC

over a wide range of voltages. Operation from split

• Very Low Supply Current Drain (0.8 mA) — power supplies is also possible and the low power Independent of Supply Voltage supply current drain is independent of the magnitude

• Low Input Biasing Current: 25 nA of the power supply voltage. These comparators also

• Low Input Offset Current: ±5 nA have a unique characteristic in that the input

common-mode voltage range includes ground, even • Offset Voltage: ±3 mV though they are operated from a single power supply

• Input Common-Mode Voltage Range Includes voltage.
