SNOSBJ3E – NOVEMBER 1999 – REVISED DECEMBER 2014
LMx39-N, LM2901-N, LM3302-N Low-Power Low-Offset Voltage Quad Comparators
1 Features
1 Wide Supply Voltage Range
• LM139/139A Series 2 to 36 VDC or ±1 to ±18 VDC
• LM2901-N: 2 to 36 VDC or ±1 to ±18 VDC
• LM3302-N: 2 to 28 VDC or ±1 to ±14 VDC
• Very Low Supply Current Drain (0.8 mA) —
Independent of Supply Voltage
• Low Input Biasing Current: 25 nA
• Low Input Offset Current: ±5 nA
• Offset Voltage: ±3 mV
• Input Common-Mode Voltage Range Includes
GND
• Differential Input Voltage Range Equal to the
Power Supply Voltage
• Low Output Saturation Voltage: 250 mV at 4 mA
• Output Voltage Compatible With TTL, DTL, ECL,
MOS, and CMOS Logic Systems
• Advantages:
– High-Precision Comparators
– Reduced VOS Drift Overtemperature

Gates
3 Description
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. 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. These comparators also
have a unique characteristic in that the input
common-mode voltage range includes ground, even
though they are 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 devices
directly interface with MOS logic— where the low
power drain of the LM339 is a distinct advantage over
standard comparators.
