LM2903N/NOPB TI Comparator | 8-PDIP | Dual, Low Power, 2-36V

Product Overview

The LM2903N/NOPB is a dual low-power voltage comparator from Texas Instruments, designed for industrial and automotive applications. It operates from a single power supply over a wide voltage range of 2V to 36V (or dual supplies ±1V to ±18V) and features low supply current drain (0.4 mA per comparator at 5V). The device is offered in an 8-PDIP package, ensuring easy integration into through-hole PCB designs. With its open-collector outputs, the LM2903N/NOPB can interface with various logic families and drive loads up to 16 mA. It is characterized for operation from -40°C to +125°C, making it suitable for harsh environments.
