概述

Description

The LM339APWR is a quad comparator integrated circuit (IC) designed for use in various electronic applications. It includes four independent, high-speed, and voltage comparators, which can be used to compare analog voltage levels. The LM339 operates with a wide supply voltage range, typically from 2V to 36V, making it versatile for different circuit designs.
Key features include a low input offset voltage, high-speed response (up to 1.3 µs), and an open-collector output configuration, allowing for easy interfacing with different logic levels. The LM339 is suitable for applications such as voltage level detection, signal conditioning, and analog-to-digital conversion.
The package type, "PWR," refers to a small outline package (SOIC-14), which is surface-mountable, facilitating compact PCB designs. Overall, the LM339APWR is ideal for designers seeking a reliable and efficient comparator solution in their projects.

Features

The LM339APWR is a quad comparator featuring the following key specifications:
