About Operational Amplifier LM358: 24 Classical Circuits



OpAmps Tutorial - What is an Operational Amplifier?

Introduction

The LM358 includes two independent, high gain, internal-frequency compensated dual operational amplifiers that are suitable for single power sources with a wide range of voltages, as well as dual-power operation modes. Under recommended operating conditions: the power supply current is independent of the power supply voltage. Its applying range includes sensor amplifiers, DC gain modules, audio amplifiers, industrial control, DC gain components, and all other situations where operational amplifiers can be used with a single power supply.

The LM358 has plug-in type and the patch type packaging which are the plastic package with double-row 8 lead wires.
