TAS5754M: Looping TAS5729M Output to DR_INx to play digital audio on the line driver

Miroslav Bozic

Part Number: TAS5729M

Hi Luis,

looking at the TAS5729M datasheet I have found that digital input cannot be routed to the line driver output. Please tell me if there is a way to somehow loop D-Class output to the DR_INx? For the application, I am developing, I need to be able to play the same audio signal that my CPU is generating on the I2S on both D-Class output and Line Driver output.

Best.

For the specific application of being to play the same audio signal from your CPU on both line out and the speaker I don't think we have a one chip solution but I would recommend using another audio dac (can search for audio dacs here http://www.ti.com/audio-ic/converters/dac/products.html )that can take your I2S data and connect the output of this DAC to the line driver. This would give you a two chip solution that would use this integrated line driver on the TAS5729MD to connect to line out, while also having a Class D speaker output.
