  • LM2903B  -  Increased performance with a wider voltage range

Description

The LM393B and LM2903B devices are the next generation versions of the industry-standard LM393 and LM2903 comparator family. These next generation comparators provide outstanding value for cost-sensitive applications featuring lower offset voltage, higher supply voltage capability, lower supply current, lower input bias current, lower propagation delay, and improved 2kV ESD performance with drop-in replacement convenience.

All devices consist of two independent voltage comparators that are designed to operate from a single power supply over a wide range of voltages. Operation from dual supplies is also 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. Quiescent current is independent of the supply voltage, and the outputs can be connected to other open-collector outputs to achieve wired-AND relationships.
