AUDIO SPECIFICATION STEREO (BTL)
Audio performance is recorded as a chipset consisting of a TASxxxx PWM Processor (modulation index limited to 97.7%) and
a TAS5614LA power stage with PCB and system configurations in accordance with recommended guidelines. Audio
frequency = 1kHz, PVDD_X = 36V, GVDD_X = 12 V, RL = 4 Ω, fS = 384 kHz, ROC = 24 kΩ, TC = 75°C, Output Filter: LDEM =
10
μH, CDEM = 1 µF, unless otherwise noted.
