The LM2903D with Analog Comparators Dual Diff is manufactured by Texas Instruments and is designed to provide cost-effective solutions for general-purpose comparator circuits. Features of the LM2903D includes a wide single-supply operating voltage range from 2.7 V to 18 V, very low bias current, excellent temperature stability, and a low supply current. The device includes two independent, high-speed comparators with on-chip hysteresis for improved noise immunity. The outputs feature rail-to-rail output swing to ensure optimal function at the supply extremes. The LM2903D is designed to provide a serious cost/performance improvement over standard bilateral comparators. It is ideal for applications such as temperature switching, level detection, battery voltage checks, and window comparator circuits.
