DESCRIPTION
Low Input Offset Current: ±5 nA
The LM139 series consists of four independent
Offset Voltage: ±3 mV
precision voltage comparators with an offset voltage
Input Common-Mode Voltage Range Includes
specification as low as 2 mV max for all four
GND
comparators. These were designed specifically to
operate from a single power supply over a wide range
Differential Input Voltage Range Equal to the
of voltages. Operation from split power supplies is

also possible and the low power supply current drain

voltage. These comparators also have a unique
characteristic in that the input common-mode voltage

ADVANTAGES
The LM139 series was designed to directly interface
with TTL and CMOS. When operated from both plus
