Konkretne katalogove udaje TDA7318:

(cut&paste)
Input Separation: min. 80 typ. 100 dB
Output Noise (BW = 20-20KHz, flat output muted all gains = 0dB): min 2.5
typ. 5 max. 15 mV
Signal to Noise Ratio (all gains = 0dB; VO = 1Vrms) typ. 106 dB
Distortion (AV =0,VIN = 1Vrms): typ. 0.01 max. 0.1 %
Distortion (AV = -20dB VIN = 1Vrms): typ. 0.09 max. 0.3 %
Distortion (AV = -20dB VIN = 0.3Vrms): typ. 0.04 %
Channel Separation left/right min. 80 typ. 103 dB
