NOTES:

7. Analog performance specs are tested with System Two

 audio measurement system by Audio Precision, using 400-Hz HPF,

20-kHz LPF at 44.1-kHz operation, 40-kHz LPF at 96-kHz operation in RMS mode.

8. fS = 96 kHz, system clock = 256 fS, oversampling ratio = ×64.

9. Minimum load on DOUT (pin 12), BCK (pin 11), LRCK (pin 10), FSYNC (pin 9).
