Note 1: The MAX9850 is 100% production tested at TA = +25°C and is guaranteed by design for TA = TMIN to TMAX.
Note 2: Full operation is defined as clocking all zeros into the DAC while the DAC, headphone outputs, and line outputs are all enabled.
Note 3: DAC performance specifications measured using the line outputs, OUTL and OUTR.
Note 4: Dynamic range is defined as the SNR of a 1kHz, -60dBFS input signal measured with an A-weighted filter, then normalized
to full scale (+60dB).
