Product Introduction

Overview

The LM358N is a dual operational amplifier produced by Fairchild Semiconductor. It integrates two independent, high-gain operational amplifiers that are internally frequency-compensated, allowing them to operate efficiently across a broad range of single power supply voltages. This versatility makes the LM358N suitable for a variety of applications, including transducer amplifiers, DC gain blocks, and conventional op-amp circuits. The component is particularly valued for its ability to operate from a single power supply, eliminating the need for dual power supplies and making it compatible with standard logic system voltages such as +5 V.
