Description for the LM2903B-Q1

The LM2903B-Q1 device is the next generation version of the industry-standard LM2903-Q1comparator family. This next generation family provides outstanding value for cost-sensitiveapplications, with features including lower offset voltage, higher supply voltage capability, lowersupply current, lower input bias current, lower propagation delay, and improved 2kV ESD performancewith improved negative input voltage handling and drop-in replacement convenience.

All devices consist of two independent voltage comparators that are designed to operatefrom a single power supply over a wide range of voltages. Operation from dual supplies also ispossible as long as the difference between the two supplies is within 2 V to 36 V, and VCC is atleast 1.5 V more positive than the input common-mode voltage. Current drain is independent of thesupply voltage. The outputs can be connected to other open-collector outputs to achieve wired-ANDrelationships.

The LM2903-Q1 and LM2903B-Q1 are Qualified for the AEC-Q100Grade 1 temperature range of -40°C to +125°C. The LM2903E-Q1 is Qualified for the AEC-Q100 Grade 0extended temperature range of -40°C to +150°C.™
