STEREO/MONO DAC INTERPOLATION AND ON-CHIP DIGITAL/ANALOG

FILTER CHARACTERISTICS

Test Conditions (unless otherwise specified): Fs = 48 kHz (Note 10).

Notes:

47. Responses are clock dependent and scale with Fs. Note that the response plots (Figures 56 to 59 on pages 131 and 132)

have been normalized to Fs and can be denormalized by multiplying the X-axis scale by Fs.
