Note 2: The MAX9867 is 100% production tested at TA = +25°C. Specifications over temperature limits are guaranteed by design.
Note 3: Clocking all zeros into the DAC, master mode, and differential headphone mode.
Note 4: DAC performance measured at the headphone outputs.
Note 5: Dynamic range measured using the EIAJ method. -60dBFS 1kHz output signal, A-weighted, and normalized to 0dBFS.
f = 20Hz to 20kHz.
Note 6: Performance measured using microphone inputs, unless otherwise stated.
Note 7: Performance measured using line inputs.
Note 8: Performance measured using DAC, unless otherwise stated. LRCLK = 8kHz, unless otherwise stated.
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.
