Overview

The LM2903-Q1 family is a dual comparator with the ability to operate up to 36 V on the supply pin. This standard device has proven ubiquity and versatility across a wide range of applications. This is due to it's very wide supply voltages range (2 V to 36 V), low Iq and fast response.

This device is AEC-Q100 qualified and can operate over a wide temperature range of –40°C to 125°C (LM2903-Q1 and LM2903B-Q1) or –40°C to 150°C (LM2903E-Q1).

The open-drain output allows the user to configure the output's logic low voltage (VOL) and can be utilized to enable the comparator to be used in AND functionality.

The "B" versions add dedicated ESD protections on all the pins for improved ESD performance as well as improved negative input voltage handling. Please see Application Note SNOAA35 for more information
