PVDD_X = 18 V, BTL mode, RL = 8 , ROC = 22 K, CBST = 33-nF, audio frequency = 1 kHz, AES17 filter,
FPWM = 384 kHz, ambient temperature = 25°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.
