SLES190 – DECEMBER 2006
AUDIO SPECIFICATIONS (Single-Ended Output)
PVDD_X = 18 V, GVDD = VDD = 12 V, SE mode, R_L = 3 Ω, R_OC = 22 KΩ, C_BST = 33-nF, 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.

(1) SNR is calculated relative to 0-dBFS input level.
(2) Actual system idle losses are affected by core losses of output inductors.
