... The dominant source of this noise is the buried Zener, contributing approximately 100 nV/√Hz. By comparison, the contribution of the op amp is negligible. Figure 5 shows the 0 noise of a typical AD587. The noise measurement is made with a band-pass filter made of a 1-pole high-pass filter with a corner frequency at 0.1 Hz and a 2-pole low-pass filter with a corner frequency at 12 ...

... Figure 15 shows that varying the load several milliamperes changes the output by only a few microvolts. 2µs TEMPERATURE PERFORMANCE The AD587 is designed for precision reference applications where temperature performance is critical. Extensive tempera- ture testing ensures that the device’s high level of performance is maintained over the operating temperature range. ...
