XD239 – Quad Voltage Comparator – Xinluda

About this part

The Xinluda XD239 is a low-power quad differential voltage comparator that integrates four independent comparators in a single SOP-14 package. Part of the industry-standard LM239 comparator family, the XD239 is designed to operate from a single power supply over a wide voltage range, making it a flexible choice for level detection, zero-crossing detection, and signal-conditioning tasks in both consumer and industrial electronics. The device belongs to the same quad-comparator family as the Xinluda XL239, with the “XD” prefix denoting Xinluda’s alternate marking designation for the part.

Key Features

• Four independent voltage comparators in one package
• Single-supply operation from 2V to 30V (maximum supply rating up to 36V)
• Low input offset voltage (5mV max)
• Low input bias current (typically 25nA)
• Low supply current: 300µA per comparator (typical)
• Open-collector output, TTL/MOS/CMOS compatible
• Common-mode input voltage range includes ground
• Built-in ESD protection
• Operating temperature range: -25°C to +85°C
• SOP-14 surface-mount package

Applications

• Single- and split-supply voltage level detection
• Zero-crossing and threshold detection
• Battery and power-supply monitoring
• Window comparators and limit detectors
• Analog-to-digital signal conditioning
• Industrial control and instrumentation
