BURR-BROWN's REF200 provides in one
8-pin DIL package two Independent current sources,
either of which can supply 100 µA,
and a 1:1 current mirror. The pinout of the
device is shown in here. Note that there
are no pins for connecting a supply voltage.
The correct operation of the current sources
is, however, guaranteed when the potential
across the source is not less than 2.5 V. The
average drift with temperature is only
25 p.p.m./K The output impedance is not less
than 100 MΩ. The operating voltage must not
exceed 40 V.
