LM2901 Overview

The LM2901 comparator is designed for use in level detection, low−level sensing and memory applications in consumer, automotive, and industrial electronic applications. The LM2901 series consists of four independent high-precision voltage comparators with a low offset voltage of 2 for all four comparison mV maximum specifications. These were canceled specifically signed to work in a wide voltage range from a single power supply.

This article provides you with a basic overview of the LM2901 Quad Comparator, including its pin descriptions, features and specifications, etc., to help you quickly understand what LM2901 is.

Frequently Asked Questions

What is the difference between LM2901 and LM2904?
LM2901 is a low-power, low-offset voltage quad comparator. LM2904 is a low-power dual operational amplifier.
What is the difference between LM2901DT and LM2901PT?
LM2901DT and LM2901PT are packaged differently. LM2901DT is SO-14 package (small outline package). LM2901PT is in TSSOP-14 package (thin shrinking SOP package).
Since LM2901 cannot be bought, can I directly replace it with LM2902? What is the difference between them?
You cannot directly replace LM2901 with LM2902. Because the pin arrangement of the two is different.
