AUDIO SPECIFICATION (BTL Operation)
TAS5176
SLES196 – JUNE 2007
PVDD_X = 24 V, GVDD = 12 V, audio frequency = 1 kHz, AES17 measurement filter, F
PWM
= 384 kHz, case temperature =
75 ° C. Audio performance is recorded as a chipset, using TAS5086 PWM processor with an effective modulation index limit of
97%. All performance is in accordance with the foregoing specifications and recommended operating conditions unless
otherwise specified.
