REF200 Dual Current Source and Current Sink

The REF200 combines three circuit building-blocks on a single monolithic chip: two 100-µA current sources and a current mirror. The sections are dielectrically isolated, making them completely independent. Also, because the current sources are two-terminal devices, they can be used equally well as c.
