Audio performance is recorded as a chipset consisting of a TAS5518 pwm processor (modulation index limited to 97.7%) and
a TAS5342LA power stage. PCB and system configuraton are in accordance with recommended guidelines. Audio frequency
= 1 kHz, PVDD_x = 32.0 V, GVDD_x = 12 V, RL = 4 , fS = 384 kHz, ROC = 22 k, TC = 75°C, Output Filter: LDEM = 10 H,
CDEM = 470 nF, unless otherwise noted.
