Product Overview
The LM2903YDT from STMicroelectronics is a dual low-power voltage comparator designed for industrial and automotive applications. It features two independent voltage comparators with open-collector outputs, capable of operating from a single power supply over a wide voltage range. The device is housed in an 8-SOIC package, offering a compact solution for space-constrained designs. With low supply current and high input impedance, the LM2903YDT is ideal for battery-powered systems and signal conditioning circuits.
