3 Description

The LM2901B-Q1 device is the next generation

version of the industry-standard LM2901x-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 four 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 V versions operate up to 32V, and the B

version operates up to 36V. All are qualified for the

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

+125°C.
