IC Current Sources

Current sources have been a well known but theoretical circuit component. Unlike voltage sources, a 0.01% accurate 2-terminal current source has been an elusive component that is not easily available and difficult to design. With the introduction of the LT3092, the current source as a drop-in component becomes a reality.

The LT3092 make an easily settable, high impedance and low temperature coefficient current source.
