LM2903B-Q1 Automotive-Qualified Dual Differential Commodity Comparator

Texas Instruments' comparator features improved 2 kV ESD performance with drop-in replacement convenience

Image of Texas Instruments' LM2903B-Q1 Automotive Qualified Dual Differential Commodity ComparatorTexas Instruments' LM2903B-Q1 is the next-generation version of the industry-standard LM2903-Q1 comparator family. This LM2903B-Q1 provides outstanding value for cost-sensitive applications with features including lower offset voltage, higher supply voltage capability, lower supply current, lower input bias current, lower propagation delay, and improved 2 kV ESD performance with drop-in replacement convenience.

The device consists of two independent voltage comparators that are designed to operate over a wide range of voltages. Operation from dual supplies is possible as long as the difference between the two supplies is within 2 V to 36 V, and VCC is at least 1.5 V more positive than the input common-mode voltage. The outputs can be connected to other open-collector outputs. The LM2903B-Q1 is qualified for the AEC-Q100 Grade 1 temperature range of -40°C to +125°C.
