ROHM Semiconductor LM2901EZ/LM2903EZ Ground-Sense Comparators

ROHM Semiconductor LM2901EZ/LM2903EZ Automotive Ground-Sense Comparators are high-gain and ground-sense input comparators. These are monolithic ICs that integrate quad independent comparators on a single chip. The operating voltage range is wide, from 3V to 36V. The ROHM Semiconductor LM2901EZ/LM2903EZ Comparators are well-suited for automotive applications, such as engine control units, electric power steering, and anti-lock braking systems, because these applications have low supply current requirements.
