ROHM Semiconductor Automotive LM2903EYxxx-C EMARMOUR™ Comparators
ROHM Semiconductor Automotive LM2903EYxxx-C EMARMOUR™ Ground Sense Comparators are high-gain, monolithic ICs that integrate a dual-independent comparator onto a single chip. The device features a 3V to 36V wide operating voltage range. The LM2903EYxxx-C is ideal for automotive requirements such as an engine control unit, an electric power steering, and an anti-lock braking system via a low supply current. Additionally, the ROHM LM2903EYxxx-C EMARMOUR Comparators offer the advantage of EMI tolerance, making it easier to replace with conventional products or simpler to design EMI.
