LM2903WYDT ST Comparators

The LM2903WYDT is an automotive-grade (AEC-Q100) low-power dual differential comparator from STMicroelectronics in SO-8 surface-mount package, designed for single or split supply operation with wide voltage range. For selection, verify single supply from 2V to 36V or dual supplies from ±1V to ±18V, response time of 1.3µs typical, low supply current of 0.4mA per comparator, wide common-mode range including ground for single-supply operation, TTL/CMOS compatible outputs, and operating temperature from -40°C to +125°C with automotive qualification. Features include low power consumption, low input bias current, and differential input voltage range equal to power supply voltage. Ideal for automotive level detection (over/undervoltage protection), zero-crossing detectors, window comparators for sensor monitoring, oscillator circuits, and any general-purpose voltage comparison requiring automotive-grade reliability with dual comparator configuration.
