D VOLTAGE OUTPUT NONLINEARITY VERSUS TEMPERATURE When using a voltage reference with data converters, it is impor- tant 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 understand the impact such a drift can have on a data converter, refer to Figure 5 where the measured drift characteristic is normalized to the endpoint 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.

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 phenomenon can be quantified by measuring the change in the +25 °C output voltage after temperature excursions from +125 °C to +25°C, and from –40°C to +25 °C. Figure 6 displays the distribution of the AD1582 output voltage hysteresis. ppm –700 –450 –200 50 300 550 0 10 20 30 40 50 60 70 80 Figure 6. Output Voltage Hysteresis Distribution SUPPLY CURRENT VERSUS TEMPERATURE The quiescent current for the AD1582/AD1583/AD1584/AD1585 family of references varies slightly over temperature and input supply range. Figure 7 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 µA/V, making this device extremely attractive for use in applications where there may be wide varia- tions in supply voltage and a need to minimize power dissipation.

Typical Supply Current over Temperature SUPPLY VOLTAGE One of the ideal features of the AD1582/AD1583/AD1584/AD1585 is low supply voltage headroom. The parts can operate at supply voltages as low as 200 mV above VOUT and up to 12 V. However, if negative voltage is inadvertently applied to VIN with respect to ground or any negative transient, >5 V is coupled to VIN and the device may be damaged. |
