LM139AD +BOM

Precision quad differential comparator, military grade

LM139AD Information

Description

Here's a concise introduction to the LM139AD: The LM139AD is a quad differential comparator from Fairchild Semiconductor Corporation. It's a precision comparator with open-drain outputs, designed for low power consumption and high accuracy applications. With a wide input common-mode voltage range of 2-30V, it can operate in various environments. The device features high slew rate and low input offset voltage, making it suitable for threshold detection, level shifting, motor control, pulse-width modulation, and sensor interfacing. Its high precision and industrial-grade robustness make it ideal for use in precision and industrial control systems, as well as signal conditioning circuits. Packaged in a 14-pin SOIC (Small Outline Integrated Circuit) package, the LM139AD is an efficient and reliable solution for a wide range of applications.

Features

According to the product information, the features of LM139AD are:

  • Quad differential comparator with open-drain outputs
