Weiss Enginering Ltd. DAC501-4ch/DAC502-4ch
D/A Converter chip
Over-sampling multi-bit sigma-delta converter - Two converters per audio channel.
Measurements XLR/RCA Output
The measurements below have been taken at the following conditions (unless noted otherwise):
1 kHz measurement frequency, maximum selectable output level, 192 kHz sampling frequency (Fs),
22 kHz measurement bandwidth, unweighted, 0 dBr equals the output level at 0 dBFS input.
Frequency Response:
Fs = 44.1 kHz , 0 Hz...20 kHz : within ± 0.25 dB
Fs = 88.2 kHz , 0 Hz...20 kHz : within ± 0.25 dB
Fs = 88.2 kHz , 0 Hz...40 kHz : within ± 1 dB
Fs = 176.4 kHz , 0 Hz...20 kHz : within ± 0.25 dB
Fs = 176.4 kHz , 0 Hz...40 kHz : within ± 1 dB
Total Harmonic Distortion plus Noise (THD+N):
-116 dBr at -3 dBFS input level
-128 dBr at -40 dBFS input level
-128 dBr at -70 dBFS input level
Linearity:
At 0 dBFS to -120 dBFS input level: less than
± 0.2 dB deviation from ideal
Spurious components (including harmonics):
At 0 dBFS input level, maximum output level,
1 kHz , all components at less than -120 dB
At 0 dBFS input level, maximum output level, 4 kHz , all components at less than -120 dB
Crosstalk:
Better than 110 dB,
20 Hz...20 kHz
Inter channel Phase Response:
± 0
