Note 2:
The MAX9880A 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. Differential headphone mode.
Note 4:
DAC performance measured at 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 line inputs to line outputs.
Note 9:
Performance measured using DAC. fMCLK = 12.288MHz, fLRCLK = 48kHz, unless otherwise stated.
Note 10: LRCLK can be any rate in the indicated range. Asynchronous or noninteger MCLK/LRCLK ratios can exhibit some full-
scale performance degradation compared to synchronous integer-related MCLK/LRCLK ratios.
Note 11: In master-mode operation, the accuracy of the MCLK input proportionally determines the accuracy of the sample clock
rate.
Note 12: CB is in pF.
