1. Description
LM393DR device is next The first generation industry standard version LM393 And LM2903 comparator series. These next The first-generation B version comparator has a lower offset Voltage, higher power supply voltage capability, lower power supply Current, lower input bias current, lower extension Delayed and improved 2 kV ESD performance and input Robustness is achieved through dedicated ESD clamps. This LM393B and LM2903B can be directly replaced LM293, LM393 and LM2903, suitable for "A" and "V" achievement. All devices are powered by two independent voltages Comparator designed to operate from one Single power supply, wide voltage range. Quiescent current has nothing to do with the power supply Voltage.
