– Surface Mount, 48-Pin, 7-mm × 7-mm discrete audio channels and seamless integration to
HTQFP Package most di*al audio processors and MPEG decoders.
– Thermal and Short-Circuit Protection The device accepts a wide range of input data and
– Support for AD or BD Mode data rates. A fully programmable data path routes
these channels to the internal speaker drivers.
The TAS5711 is an I2S slave-only device receiving all
clocks from external sources. The TAS5711 operates
with a PWM carrier between 384-kHz switching rate
and 352-KHz switching rate depending on the input
sample rate. Oversampling combined with a
fourth-order noise shaper provides a flat noise floor
and excellent dynamic range from 20 Hz to 20 kHz
