TAS5717

illustrate

The TAS5717/TAS5719 is a 10-W/15-W, high-efficiency, digital audio power-driven stereo bridged speaker amplifier. A serial data input allows for processing 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 TAS5717 / 9 was the only device for a slave to receive all clocks from external sources. There is a 384 kHz switching frequency and a 352 kHz switching frequency between the operating TAS5717/TAS5719, and the input sampling rate depends on the PWM carrier. Oversampling combined with a fourth-order noise shaper provides a unit noise substrate from 20 Hz and an excellent dynamic range of 20 kHz.
