AD584
The AD584 can also be used in a two-terminal mode to develop
a positive reference. V
positive supply through an appropriate supply resistor. The perfor-
mance characteristics will be similar to those of the negative
two-terminal connection. The only advantage of this connection
over the standard three-terminal connection is that a lower primary
supply can be used, as low as 0.5 V above the desired output
voltage. This type of operation will require considerable attention
to load and primary supply regulation to be sure the AD584 always
remains within its regulating range of 1 mA to 5 mA (2 mA to 5 mA
for operation beyond 85°C).
10 V REFERENCE WITH MULTIPLYING CMOS D/A OR
A/D CONVERTERS
The AD584 is ideal for application with the entire AD7520 series
of 10- and 12-bit multiplying CMOS D/A converters, especially
for low power applications. It is equally suitable for the AD7574
8-bit A/D converter. In the standard hook-up as shown in Figure 14,
the standard output voltages are inverted by the amplifier/DAC
configuration to produce converted voltage ranges. For example, a
+10 V reference produces a 0 V to –10 V range. If an AD308 ampli-
fier is used, total quiescent supply current will typically be 2 mA.

are tied together and to the
gain TC is guaranteed to 3 ppm/°C. Thus, using the AD584L
(at 5 ppm/°C) as the 10 V reference guarantees a maximum
full-scale temperature coefficient of 8 ppm/°C over the commer-
cial range. The 10 V reference also supplies the normal 1 mA
The AD584 will normally be used in the –10 V mode with the
AD7574 to give a 0 V to +10 V ADC range. This is shown in
Figure 16. Bipolar output applications and other operating details
can be found in the data sheets for the CMOS products.
PRECISION D/A CONVERTER REFERENCE
The AD562, like many D/A converters, is designed to operate with
a 10 V reference element (Figure 15). In the AD562, this 10 V
reference voltage is converted into a reference current of approxi-
mately 0.5 mA via the internal 19.95 kΩ resistor (in series with
the external 100 Ω trimmer). The gain temperature coefficient of
the AD562 is primarily governed by the temperature tracking of
the 19.95 kΩ resistor and the 5 kΩ/10 kΩ span resistors; this
