AUDIO SPECIFICATIONS (Single-Ended Output) (continued)
PVDD_X = 32 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.
