AUDIO SPECIFICATIONS (Single-Ended Output)
PVDD_X = 35 V, GVDD = VDD = 12 V, SE mode, R
L
= 4 Ω, audio frequency = 1 kHz, AES17 filter, F
PWM
= 384 kHz, case temperature = 75°C,
unless otherwise noted. Audio performance is recorded as a chipset, using TAS5086 PWM processor with an effective modulation index limit of
96.1%. All performance is in accordance with recommended operating conditions unless otherwise specified.
