Texas Instruments  TAS5751MDCAR

The TAS5751M device is an efficient, digital-input audio amplifierfor driving stereo speakers configured as a bridge tied load (BTL). In parallel bridge tied load(PBTL) in can produce higher power by driving the parallel outputs into a single lower impedanceload. One serial data input allows processing of up to two discrete audio channels and seamlessintegration to most digital audio processors and MPEG decoders. The device accepts a wide range ofinput data and data rates. A fully programmable data path routes these channels to the internalspeaker drivers.

The TAS5751M device is a slave-only device receiving all clocks fromexternal sources. The TAS5751M device operates with a PWM carrier between a384-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 excellentdynamic range from 20 Hz to 20 kHz.
