(4)Analog performance specs are measured in the averaging mode using the System Two audio measurement system by Audio Precision .
(5)These specs are measured under the condition that the OVR1, OVR0 n mode registers are set to (0,1). (The oversampling rate of the modulator
is 64 fS.) If the OVR1, OVR0 are (0,0) (32 fS oversampling: default), the specs are the same as at fS = 96 kHz.
