Hello!
I am designing a high fidelity player and recorder. As my design is pretty complex, containing several BGA processors, eMMC and being a 8 layers pcb, any additional design iteration will be time and budget consuming, so, some help from you will be greatly appreciated.
The problem will be: I am using 3 PCM 1794 channels for L and 3 channels for R in parallel, so, the Rout seen by the OPA413x will be 806 Ohm : 3. I need to use 2 TPA6120A2 bridged or parallel, one as a L channel and the other one as a R channel amplifiers, and I would like to know what gain settings / R values would you suggest for such aconfigurations in 4 versions: 32Ohm, 150 Ohm, 300 Ohm and 600 Ohm loads. I insist in having one TPA6120A2 per channel, either bridged or parallel, as I want more power than a single chip in stereo mode could deliver. What should I expect be the maximum power that I could get from the TPA6120A2 in these configurations?
Thank you so much for your help!
