“We often see the LM741 circuit in many projects. Sure, You can do them. But… Will it is more fun if you understand how it works?
Do not worry at all. I always try to work it easy for you.
… Ha..Ha. I know a little. But like to share.
LM741 or uA741 or called 741 is a type of op-amps. They are a high-performance operational amplifier on a single chip.
From advances of an integrated circuit. The op-amp can be on tiny silicon sheets. They are in a plastic package DIP-8 of Fairchild, Since the year 1965.
And the op-amp became number 741 in the second year, Fri 1968.
It is still popular today.”
