In some applications, a varying load may be both resistive and capacitive in nature, or the load may be connected to the AD586 by a long capacitive cable. 00529-016 Figure 17. Typical Load Regulation Characteristics Figure 15 and Figure 16 display the output amplifier characteristics driving a 1000 pF, 0 mA to 10 mA load.
TEMPERATURE PERFORMANCE
The AD586 is designed for precision reference applications where temperature performance is critical. Extensive tempera-

Some confusion exists with defining and specifying reference voltage error over temperature. Historically, references have 00529-014 Figure 15. Capacitive Load Transient Response Test Circuit been characterized using a maximum deviation per degree Celsius, that is, ppm/°C. However, because of nonlinearities in temperature characteristics that originated in standard Zener references (such as “S” type characteristics), most manufacturers have begun to use a maximum limit error band approach to specify devices. This technique involves measuring the output at three or more different temperatures to specify an output volt- age error band. Rev.
