The comparator operates from a single supply of 2V to 36V or dual supplies of ±1V to ±18V, covering the common automotive battery rails (12V nominal, 24V truck) and 5V logic rails without an extra regulator. Maximum quiescent current is 2.5mA across all four channels, and the input bias current is 0.25µA max at 5V, which keeps the error term small when using high-impedance sensor dividers.

Frequently asked questions
Is LM2901AVQPWRG4Q1 a direct replacement for LM2901VQPWRG4?
The LM2901AVQPWRG4Q1 is the automotive-grade (AEC-Q100) variant of the base LM2901 family. It can replace the non-automotive version in any design that needs the wider temperature grade.
