The TAS5751M device is an efficient, digital-input audio amplifier for 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 impedance load. 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 and data rates. A fully programmable data path routes these channels to the internal speaker drivers.

The TAS5751M device is a slave-only device receiving all clocks from external sources. The TAS5751M device operates with a PWM carrier 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.
