Note 1: The IC is 100% production tested at T
Note 2: Analog supply current = I
Note 3: Clocking all zeros into the DAC. Slave mode.
Note 4: Dynamic range measured using the EIAJ method. -60dBFS, 1kHz output signal, A-weighted and normalized to 0dBFS.
Note 5: Gain measured relative to the 0dB setting.
Note 6: The filter specification is accurate only for synchronous clocking modes, where NI is a multiple of 0x1000.
Note 7: 0dBFS for DAC input. 1V
Note 8: LRCLK may be any rate in the indicated range. Asynchronous or noninteger MCLK/LRCLK ratios may exhibit some full-
Note 9: In master-mode operation, the accuracy of the MCLK input proportionally determines the accuracy of the sample clock rate.
Note 10: CB is in pF.
