This approach ensures that the variations of the precision −10.000 V output. The +VIN pin is tied to at least a output voltage that occur as the temperature changes within the +3.5 V supply, the output pin is grounded, and the AD587 specified range are contained within a box whose diagonal has a ground pin is connected through a resistor (RS) to a −15 V slope equal to the maximum specified drift. The position of the supply. The −10 V output is taken from the ground pin (Pin 4) box on the vertical scale changes from device to device as initial instead of VOUT. It is essential to arrange the output load and the error and the shape of the curve vary. The maximum height of supply resistor (RS) so that the net current through the AD587 is the box for the appropriate temperature range and device grade between 2.5 mA and 10.0 mA (RS should be kept below 1 kΩ). is shown in Figure 16.
