Add TPA6130A2RTJ

Adam Heinrich requested to merge github/fork/adamheinrich/tpa6130a2 into master

Stereo headphone amplifier with I2C volume control by TI.

There are two versions of the IC (BGA and QFN), this only includes the RTJ (WQFN-20) footprint.

I deliberately renamed pins LEFTINP/LEFTINM to LIN+/- and RIGHTINP/RIGHTINM to RIN+/- for clarity.

Also, pins 12 (AVDD) and 3, 9, 10, 13 (AGND) are called Vdd/GND in the datasheet but the datasheet clearly says they are Analog power/ground so I renamed them to distinguish them from pins 20 (Charge pump Vdd) and 19 (Charge pump GND).

All contributions to the kicad library must follow the KiCad library convention

Thanks for creating a pull request to contribute to the KiCad libraries! To speed up integration of your PR, please check the following items:

  • Provide a URL to a datasheet for the symbol(s) you are contributing
  • An example screenshot image is very helpful
  • Ensure that the associated footprints match the official footprint library
    • A new fitting footprint must be submitted if the library does not yet contain one.
  • If there are matching footprint PRs, provide link(s) as appropriate
  • Check the output of the Travis automated check scripts - fix any errors as required
  • Give a reason behind any intentional library convention rule violation.
