Overview
The LM358AN, produced by onsemi, is a single supply dual operational amplifier that offers several distinct advantages over standard operational amplifier types, particularly in single supply applications. It is equivalent to one-half of the LM324 and is designed using the circuit designs perfected for quad operational amplifiers. This dual op-amp features low power drain, a common mode input voltage range extending to ground/VEE, and the ability to operate on either single or split supply configurations. The LM358AN can operate at supply voltages ranging from 3.0 V to 32 V, making it versatile for various applications.
