AD588
NOISE PERFORMANCE AND REDUCTION
The noise generated by the AD588 is typically less than 6 μV p-p
over the 0.1 Hz to 10 Hz band. Noise in a 1 MHz bandwidth is
approximately 600 μV p-p. The dominant source of this noise is
the buried Zener, which contributes approximately 100 nV/√Hz. In
shows the 0.1 Hz to 10 Hz noise of a typical AD588.
If further noise reduction is desired, an optional capacitor, C N ,
can be added between the NOISE REDUCTION pin and
This forms a low-pass filter with the 4 kΩ R B on the output of
the Zener cell. A 1 μF capacitor has a 3 dB point at 40 Hz and
reduces the high frequency noise (to 1 MHz) to about
200 μV p-p. Figure 8 shows the 1 MHz noise of a typical AD588
both with and without a 1 μF capacitor.
Note that a second capacitor is needed in order to implement

mode (Figure 6). The noise reduction capacitor is limited to
0.1 μF maximum in this mode.
