The LM339ADRE4 is a high-performance, low-power quad differential comparator manufactured by Texas Instruments. This precision device is designed to operate from a single power supply over a wide range of voltages, or from dual supplies for systems that require a bipolar supply operation.

Key Features

• Wide Supply Range: The LM339ADRE4 can be powered by a supply voltage ranging from 2V to 36V for single supply operations, or ±1V to ±18V for dual supply configurations. This flexibility makes it suitable for a variety of applications.
• Low Supply Current Drain: The device is optimized for low power consumption, drawing minimal current, which is independent of the magnitude of the power supply voltage.
• Input Common-Mode Voltage Range: It includes the ground potential (V₀) in its input common-mode voltage range, even when operated from a single power supply voltage.
• Offset Voltage: The LM339ADRE4 features low input offset voltage, allowing for more precise comparisons.
• Output Compatibility: The open collector outputs can be connected to other open-collector outputs to achieve wired-AND relationships, providing versatility in output configurations.
• Package: It is available in a small-outline package, making it suitable for space-constrained applications.
