Product Introduction

Overview

The LM239PT, produced by STMicroelectronics, is a low-power quad voltage comparator. This device is part of the LM139, LM239, and LM339 family, known for their precision and versatility. Each comparator in the LM239PT is designed to operate from a single power supply over a wide range of voltages, from +2 to +36 V, or from dual supplies ranging from ±1 V to ±18 V. The input common-mode voltage range includes ground, even when operated from a single power supply voltage, making it highly adaptable for various applications.
