STEREO/MONO DAC INTERPOLATION AND ON-CHIP DIGITAL/ANALOG
FILTER CHARACTERISTICS
Test Conditions (unless otherwise specified): Fs = 48 kHz
.
Notes:
47. Responses are clock dependent and scale with Fs. Note that the response plots (Figures
to
on pages
and
)
have been normalized to Fs and can be denormalized by multiplying the X-axis scale by Fs.
