Hi Guys! I hope you’re well today. Happy to see you around. In this post today, I’ll walk you through the Introduction to LM747.
LM747 is a general-purpose dual-operational amplifier IC. This chip contains two operational amplifiers on board and belongs to the LM’xx’ family where LM stands for linear monolithic. In this chip, analog components are incorporated into silicon.
I suggest you buckle up as I’ll detail the complete Introduction to LM747 covering datasheet, pinout, features, equivalents, and applications. Let’s jump right in.
