This is simple but powerful bass, treble, volume control is made by General Op-Amp IC LM741. The input voltage is 12V, but it will also work with 9V and 6V. This has inbuilt pre-amplifier also. Left ...

What is the LM741 operational amplifier? According to the datasheet LM741 IC is a general purpose single operational amplifier. The UA741 is a high performance monolithic operational amplifier ...

50 years ago a young Brit joined Fairchild where he was to design one of the most famous ICs ever made – the 741 op amp. Dave Fullagar had been working for the RRE and answered a Transitron ad. Tom ...

[Stoppi] always has exciting projects and, as you can see in the video below, the latest one is a very simple magnetic levitator design. The design is classic and simple: a 5 V regulator IC, a Hall ...

A comparator is a great circuit because it provides a near ideal transition between the analog and digital domains. The comparator looks at two linear input signals and gives a digital output that’s ...
