This circuit is from an old documentation, making use of an operational of the time. The circuit can be adapted to use modern components. The power supply must be symmetrical.
This circuit is used to match a high impedance input source with a low impedance output device...
This crystal-controlled oscillator was obtained from an American 1980s documentation. The circuit...
We found this adapter in a 1970s American documentation on instrumentation. It is suitable for analog...
