Data Sheet
PERFORMANCE OVER TEMPERATURE
Each AD584 is tested at three temperatures over the ?55°C to
+125°C range to ensure that each device falls within the maximum
error band (see Figure 6) specified for a particular grade (that is, S
and T grades); three-point measurement guarantees performance
within the error band from 0°C to 70°C (that is, J and K grades).

supply or ground. Figure 7 shows the output voltage vs. the
output current characteristics of the device. Source current is
displayed as negative current in the figure, and sink current is
displayed as positive current. The short-circuit current (that is,
0 V output) is about 28 mA; however, when shorted to 15 V, the
sink current goes to approximately 20 mA.
The error band guaranteed for the AD584 is the maximum
deviation from the initial value at 25°C. Thus, given the grade
of the AD584 , the maximum total error from the initial tolerance
plus the temperature variation can easily be determined. For
example, for the AD584 T, the initial tolerance is ±10 mV, and
the error band is ±15 mV. Therefore, the unit is guaranteed to
be 10.000 V ± 25 mV from ?55°C to +125°C.

OUTPUT CURRENT CHARACTERISTICS
The AD584 has the capability to either source or sink current
and provide good load regulation in either direction; although,
it has better characteristics in the source mode (positive current
into the load). The circuit is protected for shorts to either positive

180 μs, and there is no long thermal tail appearing after the point.
