What is IC 339?

The IC 339, also popularly written as LM339, is a quad comparator IC. Meaning, it includes 4 separate voltage comparators whose inputs and outputs are appropriately terminated via the respective external pins of the IC package, as shown below.

Is IC 339 is a positive variable voltage regulator?

The IC LM399 has positive and negative pins which are pin-3 and pin12 as shown in the circuit. Simultaneously, the voltage supply from the battery will flow through the potentiometer VR1 to the non- inverting terminals (pin5) of the IC.

How does a LM339 comparator work?

LM339 IC compares the values of two inputs against each other. When the AC signal crosses the zero-reference voltage, the output of comparator changes. The diode protects the chip from damage when the input voltage goes below the range specified for common-mode input voltage.

What kind of circuit is the LM339 used for?

LM339 (Quad differential comparator) consist of four independent voltage comparators. It is a common integrated circuit and is mainly used in high-voltage digital logic gate circuits. Using LM339 can easily form various voltage comparator circuits and oscillator circuits. Figure (a) shows a basic single limit comparator.

How big is an integrated circuit ( IC )?

Size of an IC The size of the integrated chip varies between 1 square mm to more than 200 mm. Integration of an IC Integrated chips get their name because they combine different devices on the same chip.

What is the voltage range of STMicroelectronics LM339 quad voltage comparator?

Wide single supply voltage range or dual supplies for all devices: +2 to +36 V or ±1 V to ±18 V Speed up your design by downloading all the EDA symbols, footprints and 3D models for your application. You have access to a large number of CAD formats to fit with your design toolchain.

What are the functions of an integrated circuit?

It is very small when compared to the standard circuits, which are made of independent circuit components. The most commonly used IC is the monolithic integrated circuit. Integrated circuits can function as an oscillator, amplifier, microprocessor or even as a computer memory.
