AD1859
TYPICAL PERFORMANCE
Figures 24 through 27 illustrate the typical analog performance
of the AD1859 as measured by an Audio Precision System One.
Signal-to-Noise (dynamic range) and THD+N performance is
shown under a range of conditions. Note that there is a small
variance between the AD1859 analog performance specifica-
tions and some of the performance plots. This is because the
Audio Precision System One measures THD and noise over a
20 Hz to 24 kHz bandwidth, while the analog performance is
specified over a 20 Hz to 20 kHz bandwidth (i.e., the AD1859
performs slightly better than the plots indicate). Figure 28
shows the power supply rejection performance of the AD1859.
The channel separation performance of the AD1859 is shown in
Figure 29. The AD1859’s low level linearity is shown in Figure
30. The digital filter transfer function is shown in Figure 31.
