... The AD586 offers a noise reduction pin that can be used to further reduce the noise level generated by the buried Zener. The AD586 is recommended for use as a reference for 8-, 10-, 12-, 14-, or 16-bit DACs that require an external precision reference. The device is also ideal for successive approximation ...

... band. Noise MHz bandwidth is approximately 200 µV p-p. The dominant source of this noise is the buried Zener, which contributes approximately 100 nV/√Hz. By comparison, contribution by the op amp is negligible. Figure 7 shows the 0 noise of a typical AD586. The noise measurement is made with a band-pass filter made of a 1-pole 6 V high-pass filter with a corner frequency at 0 ...

... OUT Figure 14. Fine-Scale Setting for Transient Load 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. Figure 15 and Figure 16 display the output amplifier characteristics driving a 1000 pF load. ...
