The LM339ADBR is a quad comparator integrated circuit (IC) component that is commonly used in various electronic applications. It incorporates four independent voltage comparator circuits within a single package, making it ideal for systems that require multiple comparators. Here's an overview of the LM339ADBR along with its key features:
1. Overview:
- The LM339ADBR is part of the LM339 series of quad comparators produced by Texas Instruments.
- It operates on a single power supply voltage ranging from 2V to 36V. However, it can also work with a dual power supply configuration.
- The IC consists of four independent voltage comparators with open-drain outputs.
- Each comparator has two inputs, namely the inverting (-) and non-inverting (+) inputs, and a single output. It provides a high output when the voltage at the non-inverting input is greater than the voltage at the inverting input; otherwise, it provides a low output.
- The LM339ADBR is available in an SOIC (Small Outline Integrated Circuit) package, which is compact and convenient for integration onto circuit boards.
2. Key Features:
- Wide operating voltage range: With a voltage range of 2V to 36V, the LM339ADBR is compatible with a wide variety of power supply configurations.
- Low input currents: The IC offers a very low input bias current, typically 25nA, which helps minimize the power consumption of the overall system
