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 drop-

in 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.
