NOTES: (1) Binary Two’s Complement coding. (2) Ratio of (Distortion
+ Noise
) / Signal
. (3) D/A converter sample frequency (8 x 44.1kHz; 8
x
oversampling).
(4) D/A converter output frequency (signal level). (5) Offset error at bipolar zero. (6) Measured using an OPA627 and 5k
feedback and an A-weighted filter.
