AUDIO CHARACTERISTICS (BTL)
Audio performance is recorded as a chipset consisting of a TAS5518 PWM processor (modulation index limited to 97.7%)
and a TAS5631 power stage. PCB and system configurations are in accordance with recommended guidelines. Audio
frequency = 1 kHz, PVDD_X = 50 V, GVDD_X = 12 V, RL = 4 , fS = 384 kHz, ROC = 22 k, TC = 75°C;
output filter: LDEM = 7 mH, CDEM = 680 nF, MODE = 000, unless otherwise noted.
