Typical Performance Characteristics
Figures 1 through 4 illustrate the typical performance of the
AD1857/AD1858 as measured by an Audio Precision System
Two. Signal-to-Noise (dynamic range) THD+N performance is
shown under a range of conditions. Figure 5 shows the power
AD1857/AD1858
supply rejection performance of the AD1857/AD1858. The
channel separation performance of the AD1857/AD1858 is
shown in Figure 6. The digital filter transfer function is shown
in Figure 7.
