ANALOG CHARACTERISTICS (CONTINUED)

Notes: 1. Triangular PDF Dithered Data

2. AUTO-MUTE active. See parameter definitions

3. The passband and stopband edges scale with frequency. For input sample rates, Fs, other than 48 kHz,

the passband edge is 0.4535×Fs and the stopband edge is 0.5465×Fs.

4. Group Delay for Fs=48 kHz 25/48 kHz=520

µs

5. Specified for a fully differential output ±((AOUT+)-(AOUT-)). See Figure 12.
