Figure 10. Output Voltage vs. Temperature
VOLTAGE OUTPUT NONLINEARITY VS. TEMPERATURE
When using a voltage reference with data converters, it is
important to understand the impact that temperature drift can
have on the converter’s performance. The nonlinearity of the
reference output drift represents additional error that cannot
easily be calibrated out of the overall system. To better under-
stand the impact such a drift can have on a data converter, refer
to Figure 11 where the measured drift characteristic is normal-
ized to the end point average drift. The residual drift error of the
AD1582 of approximately 200 ppm demonstrates that this
family of references is compatible with systems that require
12-bit accurate temperature performance.

Figure 11. Residual Drift Error
OUTPUT VOLTAGE HYSTERESIS
High performance industrial equipment manufacturers may
require the AD1582/AD1583/AD1584/AD1585 family to
maintain a consistent output voltage error at +25
°
C after the
references are operated over the full temperature range. While
all references exhibit a characteristic known as output voltage
hysteresis, the AD1582/AD1583/AD1584/AD1585 family
is designed to minimize this characteristic. This phenom-
enon can be quantified by measuring the change in the
+25
°
C output voltage after temperature excursions from
+85
°
C to +25
°
C, and –40
°
C to +25
°
C. Figure 12 displays
the distribution of the AD1582 output voltage hysteresis.

SUPPLY CURRENT VS. TEMPERATURE
The quiescent current for the AD1582/AD1583/AD1584/
AD1585 family of references will vary slightly over tempera-
ture and input supply range. Figure 13 demonstrates the
typical performance for the AD1582 reference when varying
both temperature and supply voltage. As is evident from the
graph, the AD1582 supply current increases only 1.0
μ
A/V,
making this device extremely attractive for use in applica-
tions where there may be wide variations in supply voltage
and a need to minimize power dissipation.
