APPLICATIONS
BASIC VOLTAGE REFERENCE CONNECTION
The circuit in Figure 33 illustrates the basic configuration for
the ADR36x family. Decoupling capacitors are not required for
circuit stability. The ADR36x family is capable of driving
capacitive loads from 0 μF to 10 μF. However, a 0.1 μF ceramic
output capacitor is recommended to absorb and deliver the
charge as is required by a dynamic load.

Stacking Reference ICs for Arbitrary Outputs
Some applications can require two reference voltage sources,
which are a combined sum of standard outputs. Figure 34 shows
how this stacked output reference can be implemented.

Figure 34. Stacking Voltage References with the ADR36x
Two reference ICs are used and fed from an unregulated input,
V
IN
. The outputs of the individual ICs are connected in series,
which provides two output voltages, V
OUT1
and V
OUT2
. V
OUT1
is
the terminal voltage of U1, while 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 10). For
example, if both U1 and U2 are ADR361s, V
OUT1
is 2.5 V and
V
OUT2
is 5.0 V.

A Negative Precision Reference Without Precision
Resistors
A negative reference is easily generated by adding an op amp,
A1 and is configured in Figure 35. V
OUTF
and V
OUTS
are at virtual
ground and, therefore, the negative reference can be taken
directly from the output of the op amp. The op amp must be
dual-supply, low offset, and rail-to-rail if the negative supply
voltage is close to the reference output.
