AUDIO CHARACTERISTICS (BTL)
Audio performance is recorded as a chipset consisting of a TAS5518 PWM Processor (modulation index limited to 97.7%)
and a TAS5612A power stage. PCB and system configurations are in accordance with recommended guidelines. Audio
frequency = 1kHz, PVDD_X = 32.5V, GVDD_X = 12V, RL = 4, fS = 384 kHz, ROC = 30k, TC = 75°C,
Output Filter: LDEM = 7mH, CDEM = 680nF, MODE = 000, unless otherwise noted.
