XD2901 – Voltage Comparator – Xinluda

The XD2901 is a Xinluda quad differential voltage comparator (LM2901-type) in an SOP-14 package, featuring a wide supply range up to 36 V and low offset voltage. Available for quote at Pacific Component Xchange.

The XD2901 from Xinluda Information Technology Co., Ltd. is a quad differential voltage comparator that serves as a functional equivalent to the industry-standard LM2901. It integrates four independent voltage comparators designed to operate from a single power supply over a wide voltage range, making it well suited for level detection, zero-crossing detection, and general-purpose signal-conditioning tasks in both consumer and industrial electronics.

Built with dedicated ESD clamps on the inputs for ruggedness, the XD2901 delivers low input offset voltage, low input bias current, and low supply current per comparator. Its outputs are compatible with TTL, MOS, and CMOS logic, allowing straightforward interfacing across mixed-voltage systems. The device is offered in a space-saving SOP-14 surface-mount package with industry-standard LM2901 pinout for drop-in compatibility.
