The TAS5721 is an efficient, digital-input audio amplifier for
driving 2.0 speaker systems configured as a bridge tied load (BTL), 2.1 systems with two satellite
speakers and one subwoofer, or in PBTL systems driving a single speaker configured as a parallel
bridge tied load (PBTL). One serial data input allows processing of up to two discrete audio
channels and seamless integration to most digital audio processors and MPEG decoders. The device
accepts a wide range of input data formats and sample rates. A fully programmable data path routes
these channels to the internal speaker drivers.
The TAS5721 is a slave-only device, receiving all clocks from
external sources. The TAS5721 operates with a PWM carrier frequency between a
384-kHz switching rate and a 288-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.
An integrated ground centered DirectPath™ combination headphone
amplifier and 2VRMS line driver is integrated in the
