The XL741 Discrete Op-Amp Kit Soldering Kit is a faithful and functional transistor-scale replica of the μA741 op-amp integrated circuit, the classic and ubiquitous analog workhorse. An Operational Amplifier, or "op-amp" as they are commonly known, is one of the most useful and common types of analog electronic circuit building blocks.
It includes the circuit board, resistors, transistors and capacitor that make up the electrical circuit as well as printed assembly instructions. The kit also comes complete with the "IC Leg" stand, and 8 color coded thumbscrew terminal posts.
To build the XL741 kit, basic electronic soldering skill and tools are required, but no additional knowledge of electronics is presumed or required. You provide standard soldering tools: a soldering iron + solder and small ("flush") wire clippers, as well as a Phillips head screwdriver
The XL741 circuit is a direct implementation of the "equivalent circuit" from the original Fairchild μA741 datasheet, built up using discrete components like resistors and individual 2N3904 and 2N3906 transistors. It comes with terminal posts and solder points so that you can actually connect to it and build up classic and functional op-amp circuits. Using those terminal posts and solder points, you can hook up with with bare wires, lugs, alligator clips, and/or solder joints— however you see fit.
