PVDD_X = 18 V, SE mode, RL = 4 Ω, ROC = 22 kΩ, 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.
