Production Data
DAC TO HEADPHONE POWER CONSUMPTION
The following tables detail the DAC to Headphone power consumption differences and SNR differences (where applicable)
between 4 different playback conditions and 3 different biasing modes. The biasing modes are detailed in Table 45 on page 12.
Table 3 DAC to Headphone Power Consumption: Quiescent (DAC input all zeroes and OUT2VOL PGA set to 0dB)
Table 4 DAC to Headphone Power Consumption: -57dB Playback (DAC input 0dBFS 1kHz sine and OUT2VOL PGA set
to -57dB)
