XL393 – Dual Differential Comparator – Xinluda

The Xinluda XL393 is a dual independent low-offset voltage comparator (LM393-type) in an SOP-8 package, operating from 2 V to 36 V with open-collector outputs compatible with TTL, MOS, and CMOS logic.

The XL393 from Xinluda is a dual independent precision voltage comparator and a functional equivalent of the industry-standard LM393. It integrates two independent comparators designed to operate from a single power supply over a wide voltage range, while also supporting split-supply operation. With an input stage whose common-mode range includes ground, the XL393 is well suited to single-supply systems where signals must be compared against levels close to the negative rail.

Each comparator features an open-collector output, allowing outputs to be wired-OR together and interfaced directly to TTL, MOS, and CMOS logic by selecting an appropriate pull-up. The XL393 combines low input offset voltage, low input bias current, and low supply-current drain that is essentially independent of supply voltage, making it a versatile, cost-effective choice for level detection, zero-crossing detection, and threshold/window comparison circuits.
