NE GAT IVE RE FE RE NCE VOLT AGE FROM AN AD586
T he AD586 can be used to provide a precision –5.000 V output
as shown in Figure 11. T he V
IN
pin is tied to at least a +6 V
supply, the output pin is grounded, and the AD586 ground pin
is connected through a resistor, R
S
, to a –15 V supply. T he –5 V
output is now taken from the ground pin (Pin 4) instead of
V
OUT .
It is essential to arrange the output load and the supply
resistor R
S
so that the net current through the AD586 is be-
tween 2.5 mA and 10.0 mA. T he temperature characteristics
and long-term stability of the device will be essentially the same
as that of a unit used in the standard +5 V output configuration.

T he AD586 is an ideal reference for a wide variety of 8-, 12-,
14- and 16-bit A/D and D/A converters. Several representative
examples follow.

T he AD586 is ideal for applications with 10- and 12-bit multi-
plying CMOS D/A converters. In the standard hookup, as
shown in Figure 12, the AD586 is paired with the AD7545
12-bit multiplying DAC and the AD711 high-speed BiFET Op
Amp. T he amplifier DAC configuration produces a unipolar
0 V to –5 V output range. Bipolar output applications and other
operating details can be found on the individual product data
sheets.

T he AD586 can also be used as a precision reference for mul-
tiple DACs. Figure 13 shows the AD586, the AD7628 dual
DAC and the AD712 dual op amp hooked up for single supply
operation to produce 0 V to –5 V outputs. Because both DACs
are on the same die and share a common reference and output
op amps, the DAC outputs will exhibit similar gain T Cs.

Often, a design requires several reference voltages. T hree
AD586s can be stacked, as shown in Figure 14, to produce
+5.000 V, +10.000 V, and +15.000 V outputs. T his scheme
can be extended to any number of AD586s as long as the
maximum load current is not exceeded. T his design pro-
vides the additional advantage of improved line regulation
on the +5.0 V output. Changes in V
IN
of +18 V to +50 V
produces an output change that is below the noise level of
the references.
