This circuit is a driver for R-2R network of AD converters. We found it in manufacturer documentation from the 1980s. The configuration can be adapted to be used with modern operationals.
This circuit is from an old publication from 1977 and can be implemented with more modern...
This basic buffer circuit can be implemented with other operational amplifiers. The circuit is...
This circuit can be applied to other 3-terminal regulators and equivalent transistors can be used....
