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.
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.
Record operation is defined as operating the stereo ADC with the stereo external microphone inputs enabled at the 48kHz
sample rate in master mode.
Speaker output available only on the MAX9851. PV
the MAX9853.
DAC performance measured at headphone outputs.
Dynamic range measured using the EIAJ method. The input is applied at -60dBFS, f
0dBFS A-weighted.
The SNR is referred to 0dBFS A-weighted.
ADC performance measured from line inputs (unless otherwise noted).
Microphone amplifiers connected to ADC, mic inputs AC-grounded.
puts. Headphone and receiver amplifier testing performed with 32Ω 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.
