LM2903DGKR

LM2903DGKR Description

The LM2903DGKR comparator is the next generation comparator of the industry standard series LM393 and LM2903. These new B-generation version comparators feature lower offset voltage, higher supply voltage capability, lower supply current, lower input bias current, lower propagation delay, and improved 2KVESD performance and input robustness through dedicated ESD clamping. LM393B and LM2903B can replace LM293, LM393 and LM2903 as AN and V levels. All devices are composed of two independent voltage comparators, which can be operated by a single power supply in a variety of voltage ranges. The static current has nothing to do with the supply voltage.
