TAS5630 AD or BD modulation

Q: TAS5630 AD or BD modulation

Hello,

 

I have a question about the AB or BD modulation to use the TAS5630 in btl configuration.

For my application i will use long cable between the amplifier and the speaker (about 5-10 meters)

What is the best for EMC consideration?

 

Thanks

Hello,

There shouldn't be that much a difference for well designed systems, but BD modulation will typically edge out AD in a general scenario due to slightly reduced transmission of switching frequency noise.
