10-CHANNEL HIGH DEFINITION AUDIO CODEC
40dB Mic Boost Enabled THD+N
10-CHANNEL HIGH DEFINITION AUDIO CODEC
1. Ratio of Full Scale signal to noise output with -60dB signal, measured “A weighted” over a 20 Hz to a 20 KHz
2. ± 3dB limits for Line Output and 0dB gain, at -20dBV
3. Amplitude of THD+N, measured with A-weighting filter, over 20 Hz to 20 KHz bandwidth.
4. Ratio of Full Scale signal to idle channel noise output is measured “A weighted” over a 20 Hz to a 20 KHz
5. Peak-to-Peak Ripple over Passband meets ± 0.25dB limits, 48 KHz Sample Frequency.
6. Stop Band rejection determines filter requirements. Out-of-Band rejection determines audible noise.
7. The integrated Out-of-Band noise generated by the DAC process, during normal PCM audio playback, over a
