Stacking ADR5xx for User-Definable Outputs
Multiple ADR5xx parts can be stacked together to allow the
user to obtain a desired higher voltage. Figure 22a shows three
ADR550s configured to give 15 V. The bias resistor, R
BIAS
, is
chosen using Equation 3, noting that the same bias current will
flow through all the shunt references in series. Figure 22b shows
three ADR550s stacked together to give –15 V. R
BIAS
is calculated
in the same manner as before. Parts of different voltages can
also be added together, i.e., an ADR525 and an ADR550 can be
added together to give an output of +7.5 V or –7.5 V, as desired.
Note, however, that the initial accuracy error is now the sum of
the errors of all the stacked parts, as are the tempco and output
voltage change versus input current.

Adjustable Precision Voltage Source
The ADR5xx, combined with a precision low input bias op amp,
such as the AD8610, can be used to output a precise adjustable
voltage. Figure 23 illustrates the implementation of this
application using the ADR5xx. The output of the op amp,
V
OUT
,
is determined by the gain of the circuit, which is completely
dependant on the resistors,
R1
and
R2
.

An additional capacitor, C1, in parallel with R2, can be added to
filter out high frequency noise. The value of C1 is dependent on
the value of R2.
