STACKING REFERENCE ICs FOR
ARBITRARY OUTPUTS
Some applications may require two reference voltage sources
that are a combined sum of the standard outputs. Figure 34 and
Figure 35 show how these stacked output references can be
implemented.

Two reference ICs are used and fed from an unregulated input,
V
IN
. The outputs of the individual ICs that are connected in
series provide two output voltages, V
OUT1
and V
OUT2
. V
OUT1
is the
terminal voltage of U1, and V
OUT2
is the sum of this voltage and
the terminal voltage of U2. U1 and U2 are chosen for the two
voltages that supply the required outputs (see Table 5). For
example, if U1 is set to have an output of 1 V or 0.5 V, the user
can stack on top of U2 to get an output of 2 V or 1.5 V.
