LM339DR

The LM339DR is a quad differential comparator manufactured by Texas Instruments. It belongs to the LMx39/LM2901 series of four-channel voltage comparators, designed to operate from a single power supply over a wide range of voltages. The LM339DR can also operate from dual supplies, as long as the difference between the two supplies is within the specified range (typically 2 to 36V), and VCC is at least 1.5V more positive than the input common-mode voltage.

This comparator features low input bias voltage and input bias current, making it suitable for various analog signal processing tasks. It has a differential input voltage range equal to the maximum-rated supply voltage, and a low output saturation voltage. The outputs of the LM339DR can be connected to other open-collector outputs to achieve wired-AND relationships.

The LM339DR is characterized for operation from 0°C to 70°C, and it offers low supply-current drain that is independent of the supply voltage. Its common-mode input voltage range includes ground, and the outputs are compatible with TTL, MOS, and CMOS logic levels.

In summary, the LM339DR is a versatile and reliable quad differential comparator with wide voltage range, low power consumption, and compatibility with various logic levels. It is suitable for use in a wide range of applications, including automotive, industrial, and consumer electronics.
