Product Introduction

Overview

The LM258AST is a low-power dual operational amplifier produced by STMicroelectronics. This component is designed to operate from a single power supply over a wide range of voltages, making it versatile for various applications. The LM258AST features two independent, high-gain, internally frequency-compensated op amps, which are suitable for use in single power supply systems. It is particularly useful in scenarios where the input common-mode voltage range includes ground, and the output voltage can swing to ground, even with a single power supply voltage.
