• Description: Low-power, Stereo Audio Codec
• Manufacturer: Maxim Integrated Products, Inc.

Ultra-Low Power Stereo Audio Codec
ELECTRICAL CHARACTERISTICS (continued)
(V
mode, C
0dB, MCLK = 13MHz, T
Note 2: The MAX9867 is 100% production tested at T
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.
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: C
