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

comparators. These were designed specifically to

operate from a single power supply over a wide range

•

Differential Input Voltage Range Equal to the
