REF200AU/2K5

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 current sinks. The performance of each section is
individually measured and laser-trimmed to achieve
high accuracy at low cost.
The sections can be pin-strapped for currents of 50
µA, 100 µA, 200 µA, 300 µA, or 400 µA. External
circuitry can obtain virtually any current. These and
many other circuit techniques are shown in the
Application Information section of this data sheet.
The REF200 is available in an SOIC package.
