Automotive Catalog Dual Differential Comparator - LM2903-Q1

LM2903-Q1 (ACTIVE)

Automotive Catalog Dual Differential Comparator

 

Description

This device consists 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 possible, as long as the difference between the two supplies is 2 V to 36 V, and VCC is at least 1.5 V more positive than the input common-mode voltage. Current drain is independent of the supply voltage. The outputs can be connected to other open-collector outputs to achieve wired-AND relationships.
