Features
Description
This family of devices consists of four
independent precision-voltage comparators with
an offset voltage specification as low as 2 mV
maximum for LM339A, LM239A and LM139A.
Each comparator has been designed specifically
to operate from a single power supply over a wide
range of voltages. Operation from split power
supplies is also possible.
These comparators also have a unique
characteristic in that the input common mode
voltage range includes ground even though
operated from a single power supply voltage.
July 2011
Wide single supply voltage range or dual
supplies for all devices: +2 to +36 V or ±1 V to
±18 V
Very low supply current (1.1 mA) independent
of supply voltage
Low input bias current: 25 nA typ
Low input offset current: ±5 nA typ
Low input offset voltage: ±1 mV typ
Input common-mode voltage range includes
ground
Low output saturation voltage: 250 mV typ;
