1.Dynamic Range is the ratio of the full scale signal to the noise output with a -60dBFS signal as defined in AES17
as SNR in the presence of signal and outlined in AES6id, measured “A weighted” over 20 Hz to 20 kHz bandwidth.
2.Ratio of Full Scale signal to idle channel noise output is measured “A weighted” over a 20 Hz to a 20 kHz band-
width. (AES17-1991 Idle Channel Noise or EIAJ CP-307 Signal-to-noise Ratio).
3.THD+N ratio as defined in AES17 and outlined in AES6id,non-weighted, swept over 20 Hz to 20 kHz bandwidth
as required by WLP 3.09. Results at the jack are dependent on external components and will likely be 1 - 2dB
worse.
4.48 kHz or 44.1 kHz Sample Frequency. -1dB upper band limit. -3dB lower band limit.
5.Peak-to-Peak Ripple over Passband meets ± 0.125dB limits, 48 kHz or 44.1 kHz Sample Frequency. 1dB limit.
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
bandwidth 28.8 to 100 kHz, with respect to a 1 Vrms DAC output.
8.Boost gain may be within +/-2dB of target, but actual gain will always ensure that the WLP FSIV requirement will be
met and that the boost implementation will not interfere with the +/-0.5dB gain accuracy for the ADC record gain as
exposed in the ADC mux widget.
9.± 1dB limits for Line Output & 0 dB gain, at -20dBV
10.Spurious tone rejection is tested with ADC dither enabled and compared to ADC performance without dither.
11.All functions/converters active, pin complexes enabled, two FDX streams, line (10Kohm) loads. Add 24mA
analog current per stereo 32 ohm headphone.
12.One stereo DAC and corresponding pin widgets enabled (playback mode)
13.Mixer enabled
14.Idle measurement D3 set for minimum clicks/pops (biases and min. amps. on)
15.Can be set to 50% or 80% of AVdd.
16.Designed to mimic 80% and 50% of 3.3V. 80% setting is nominal 2.6V, 50% setting is nominal 1.6V
