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 and higher supply voltage capability. Additionally, 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 2V to 36V, and VCC is at least 1.5V 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.
