TAS5727

illustrate

The TAS5727 is a 25-watt, high-efficiency, digital audio-driven stereo bridged speaker power amplifier. One serial data input allows processing of up to two independent audio channels and seamless integration into most digital audio processors and MPEG decoders. The device accepts input data and various data rates. A fully programmable data path routes these internal speaker driver channels.

The TAS5727 is a slave's only device that receives all clocks from external sources. Operating TAS5727 has a switching frequency of 384 kHz and a switching frequency of 288 kHz, the input sampling rate depends on the PWM carrier. Oversampling combined with a fourth-order noise shaper provides a noise floor in units from 20 Hz and excellent dynamic range of 20 kHz.
