DESCRIPTION
The REF200 combines three circuit building-blocks
on a single monolithic chip—two 100µA current
sources and a current mirror. The sections are
dielectrically isolated, making them completely
independent. Also, since 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 50µA,
100µA, 200µA, 300µA or 400µA. External circuitry
can be used to obtain virtually any current. These and
many other circuit techniques are shown in the
Applications section of this Data Sheet.
The REF200 is available in plastic 8-pin mini-DIP
and SOIC packages.

DISCHARGE SENSITIVITY
This integrated circuit can be damaged by ESD. Burr-Brown
recommends that all integrated circuits be handled with
appropriate precautions. Failure to observe proper handling
and installation procedures can cause damage.
ESD damage can range from subtle performance degradation
to complete device failure. Precision integrated circuits may
be more susceptible to damage because very small parametric
changes could cause the device not to meet its published
specifications.
