Note 1:
DAC playback mode is defined as clocking all zeros into the DAC which operates in stereo audio mode at the 48kHz sam-
ple rate in master mode.
Note 2:
Full-duplex voice mode is defined as operating the DAC and ADC in mono 8kHz voice mode with line inputs, microphone
inputs, and an analog output enabled.
Note 3:
Record operation is defined as operating the stereo ADC with the stereo external microphone inputs enabled at the 48kHz
sample rate in master mode.
Note 4:
Speaker output available only on the MAX9851. PVDD powers only the headset autodetect circuitry when in sleep mode on
the MAX9853.
Note 5:
DAC performance measured at headphone outputs.
Note 6:
Dynamic range measured using the EIAJ method. The input is applied at -60dBFS, fIN = 1kHz. The THD+N referred to
0dBFS A-weighted.
Note 7:
The SNR is referred to 0dBFS A-weighted.
Note 8:
ADC performance measured from line inputs (unless otherwise noted).
Note 9:
Microphone amplifiers connected to ADC, mic inputs AC-grounded.
Note 10: In master-mode operation, sample clock rate is proportional to MCLK input.
Note 11: Speaker amplifier testing performed with 8
Ω resistive load in series with a 68H inductive load connected across BTL out-
puts. Headphone and receiver amplifier testing performed with 32
Ω resistive load connected to GND. Mode transitions are
controlled by toggling the amplifier on and off using the corresponding enable bit. Units expressed in dBV.
Note 12: Input signal for speaker, line output, and receiver output performance measured using line inputs.
Note 13: Line input specifications measured from line inputs to line outputs.
Note 14: CB is in pF.
