are shown under a range of conditions. Figure 16 shows the
power supply rejection performance of the AD1855. Figure 17
shows the noise floor of the AD1855. The digital filter transfer
function is shown in Figure 18. The two-tone test in Figure 19
is per the SMPTE Standard for Measuring Intermodulation
Distortion.
