The circuit is from the 1994 National Semiconductor Linear Applications Handbook but can be implemented with more modern operational amplifiers. The power supply must be symmetrical.
This power supply was originally designed to power our next circuit (CB18672E) which consists of a...
This circuit allows the control of a low intensity audio signal from an external logic signal. The...
Found in a 1964 publication, this circuit makes use of transistors from the time. It operates on...
