7.6 Audio Characteristics (BTL)

PCB and system configuration are in accordance with recommended guidelines. Audio frequency = 1 kHz, PVDD_X = 30 V, VDD = 5 V, GVDD = 5 V, RL = 4 Ω, fS = 480 kHz, TC = 75°C, Output Filter: LDEM = 10 μH, CDEM = 1 µF, AD-Modulation, AES17 + AUX-0025 measurement filters, unless otherwise noted.
PARAMETER TEST CONDITIONS MIN TYP MAX UNIT
PO Power output per channel RL = 8 Ω, 10% THD+N 60 W
RL = 4 Ω, 10% THD+N, 1-channel,
5 s duration		 110
RL = 8 Ω, 1% THD+N 50
RL = 4 Ω, 1% THD+N, 2-channels,
3 s duration		 89
RL = 4 Ω, 1% THD+N, 1-channel,
60 s duration		 89
THD+N Total harmonic distortion + noise 1 W 0.02 %
Vn Output integrated noise A-weighted, AES17 filter, Input Capacitor Grounded, Gain = 18 dB 72 μV
|VOS| Output offset voltage Inputs AC coupled to GND 20 60 mV
SNR Signal-to-noise ratio(1) A-weighted, Gain = 18 dB 108 dB
DNR Dynamic range A-weighted, Gain = 18 dB 109 dB
Pidle Power dissipation due to idle losses (IPVDD_X) PO = 0, all outputs switching, AD-modulation, TC = 25°C(2) 0.55 W
PO = 0, all outputs switching, HEAD-modulation, TC = 25°C(2) 0.38 W
(1) SNR is calculated relative to 1% THD+N output level.
(2) Actual system idle losses also are affected by core losses of output inductors.
