Measured DAC THD+N (0 dB) with VA = 5 V or 3.3 V (nominal voltage) could be -81 dB and does not
meet the -83 dB maximum specification in the Data Sheet. Measured DAC THD+N (0 dB) with VA =
3.0 V (3.3 V min.) is -79 dB and does not meet the -83 dB maximum specification in the Data Sheet.
The digital portions of the part (both ADC and DAC) will not function when MCLK divide by 1.5 is
selected and VD = 3.3 V. The following start-up sequences will correct the problem.
