The TAS5709 is a 20-W, efficient, digital audio-power amplifier for driving stereo bridge-tied speakers. 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 TAS5709 is a slave-only device receiving all clocks from external sources. The TAS5709 operates with a PWM carrier between a 384-kHz switching rate and a 352-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.

The TAS5709A is identical in function to the TAS5709, but has a unique I2C device address. The address of the TAS5709 is 0x36. The address of the TAS5709A is 0x3A.
