National Semiconductor LM193/LM293/LM393/LM2903 Dual Comparator Datasheet
The LM193 series consists of two independent precision voltage comparators with low offset voltage (as low as 2 mV) and low supply current drain. They operate from a single supply (2 V to 36 V) or split supplies and feature an input common‑mode range that includes ground.
The document provides electrical characteristics, absolute maximum ratings, ordering information, typical performance graphs, application hints, and physical dimensions for the LM193, LM293, LM393 and LM2903 devices.
