LM339ADBR

The LM339ADBR is an integrated circuit comparator manufactured by Texas Instruments. It contains four differential comparators with outputs that can be CMOS, MOS, Open-Collector, or TTL compatible. The device is housed in a 14-SSOP package suitable for surface mount mounting. It is designed for applications requiring multiple comparator channels with fast response times, such as signal processing and threshold detection circuits.

The comparator operates over a supply voltage range of 2V to 30V, making it versatile for various power supply configurations. Its typical propagation delay is 1.3 microseconds under test conditions of Vs = 5V, output = 1.3V, and load capacitance of 15pF. The device features include an offset voltage maximum of 3mV, input bias current maximum of 50nA, and quiescent current of 0.2mA per channel. It includes ground as part of the common-mode input voltage range and can handle differential input voltages up to the maximum rated supply voltage.

Designed for use in digital and analog signal comparison, the LM339ADBR is suitable for applications in industrial, automotive, and consumer electronics where multiple high-speed comparator channels are needed. Its surface-mount package facilitates compact circuit design and automated assembly.
