描述 Description

The LM2903B-Q1 device is the next generation

version of the industry-standard LM2903-Q1

comparator family. This next generation family

provides outstanding value for cost-sensitive

applications, with features including lower offset

voltage, higher supply voltage capability, lower supply

current, lower input bias current, lower propagation

delay, and improved 2kV ESD performance with dropin

replacement convenience.

All devices consist of two independent voltage

comparators that are designed to operate over a wide

range of voltages. Operation from dual supplies also

is possible as long as the difference between the two

supplies is within 2 V to 36 V, and VCC is at least 1.5

V more positive than the input common-mode voltage.

The outputs can be connected to other open-collector

outputs.

The LM2903-Q1 and LM2903B-Q1 are qualified for

the AEC-Q100 Grade 1 temperature range of -40°C to

+125°C. The LM2903E-Q1 is Qualified for the Grade

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