TI TAS5733LDCAR

The TAS5733L device is a high - efficiency digital input audio amplifier used to drive stereo speakers in a bridge - tied load (BTL) configuration. For parallel bridge - tied load (PBTL), the device can drive parallel outputs to a single low - impedance load, thus generating higher power. A serial data input can handle up to two discrete audio channels and can be seamlessly integrated with most digital audio processors and MPEG decoders. This device can accept a wide range of input data and data transfer rates. A fully programmable data path routes these channels to the internal speaker drivers. The TAS5733L device is used only as a slave device to receive all externally provided clocks. The TAS5733L device uses a PWM carrier with a switching frequency between 288kHz and 384kHz, depending on the input sampling rate. Oversampling combined with a fourth - order noise shaper provides a white noise reference and excellent dynamic range from 20Hz to 20kHz.
