Other Parts Discussed in Thread: TAS5828M

hello, I apologize for my lack of experience.
I would need an amplifier with the characteristics in the title but not finding any already made, 
I ask if I can use two of them and possibly how to connect them. For now I have only worked with tas5760. 
thanks to anyone who can give me a hand

Hello Franceso,

Using 2 TAS5828M seems like it should fit with your application needs.

Best regards,

Luis

Thanks Luis for your reply,
I looked at the datasheet of the model you told me but I can't understand the connection in the schematic between the two amps.
I give you an example, in the analog model tpa3116 on page 26 gives me a schematic that makes me understand how to connect them on these amplifiers,
I do not find anything of the kind.
thank you very much and have a nice day

Hello Francesco,

It's shown in the typical applications page. Depending on the configuration you can share the same input I2S bus or if you use a 2.1 process flow the woofer(the 0.1 PBTL) would use the Stereo 2.0 BTL channel SDOUT as SDIN.

best regards,

Luis
