3 Description

This device consists of two independent voltage

comparators that are designed to operate from a

single power supply over a wide range of voltages.

Operation from dual supplies is possible, as long as

the difference between the two supplies is 2 V to 36

V, and VCC is at least 1.5 V more positive than the

input common-mode voltage. Current drain is

independent of the supply voltage. The outputs can

be connected to other open-collector outputs to

achieve wired-AND relationships.

The LM2903-Q1 is Qualified for the AEC-Q100 Grade

1 temperature range of -40°C to +125°C. The

LM2903E-Q1 is Qualified for the AEC-Q100 Grade 0

temperature range of -40°C to +150°C.
