Audio performance is recorded as a chipset consisting of a TAS5086 pwm processor (modulation index limited to 97.7%) and
a TAS5342A power stage. PCB and system configuraton are in accordance with recommended guidelines. Audio frequency =
1 kHz, PVDD_x = 31.5 V, GVDD_x = 12 V, RL = 4 , fS = 384 kHz, ROC = 27 k, TC = 75°C, Output Filter: LDEM = 20 H,
CDEM = 1.0 F, unless otherwise noted.
