This circuit was found in the 1990 Motorola Dataar Linear. We can mount it with more modern equivalent transistors. Output transistors shall be provided with heat radiators.
This circuit is from an old operational amplifiers manual. However, the setting applies to modern...
The TDA2040 is not a common IC these days, but if you find one you can build this high quality...
This simulation shows how can we test a capacitor using a function generator and oscilloscope. The...
