TAS5753MD Stereo Audio Class-D Amplifier

Texas Instruments TAS5753MD Stereo Audio Class-D Amplifier is an efficient, digital-input audio amplifier for driving stereo speakers configured as a bridge tied load (BTL). 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 TAS5753MD is a slave-only device receiving all clocks from external sources. The amplifier operates with a PWM carrier between a 384kHz switching rate and a 288kHz 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 20Hz to 20kHz. The TAS5753MD has an integrated Directpath™ Headphone amplifier and line driver to increase the system-level integration and reduce total solution costs.
