I am building an amp based on the TPA3116D2.
I read that if I forget to attach the speaker / 1 wire slips away, there's danger of the LC filter enter resonance and fry the chip/capacitors.
I saw some protections done by attaching two diodes, which lock the output of the filters inside the voltage rail (+Vf).
I have two questions though.
With reference to this schematic
http://www.ti.com/lit/ug/slou336b/slou336b.pdfAre right- and left- usually above ground? Or does the TPA3116D2 usually push right- and left- at negative voltages?
The power supply can be as low as 5v. Does it mean that the chip can act as a "boost" converter?
If the answer to any of these two questions is "yes", then I guess the diode protection I saw is unusable / impacts the performance (the second is less critical if the supply is high)
