UNIT

(8)

Analog performance specifications are tested with System Two™ audio measurement system by Audio Precision™, using 400-Hz HPF,

20-kHz LPF for 44.1-kHz operation or 40-kHz LPF for 96-kHz operation in RMS mode.

(9)

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

(10) Minimum load on DOUT, BCK, LRCK, and FSYNC.
