Product Introduction

Overview

The LM393AWDT, produced by STMicroelectronics, is a low power dual voltage comparator designed for a wide range of applications. This device consists of two independent low voltage comparators that can operate from a single supply or split power supplies. The LM393 series is known for its ability to operate with a single power supply voltage while still allowing the input common-mode voltage range to include ground. This feature makes it highly versatile for various electronic systems.
