Other Parts Discussed in Thread: TPA3140D2
Hello,
In the datasheet of this component there are 2 example schematic layouts (page 21 and 22). Both show the AVCC beeing connected to PVCC through a 10R resistor. However, this doesn't show the required size of the 10R resistor e.g. the expected current/power to flow through this resistor. What size resistor should this be?
Also, the datasheet refers to a TPA3144D2 evaluation board for an example layout (page 29). Sadly, this board doesn't exist and a google search only shows the datasheet referring to it (TPA3144D2EVM).
Another thing, page 28 mentions 220µF or larger bulk capacitors to be used, but the example schematics use 100µF capacitors. Same for AVCC, the text mentions a 10µF cap to be used, but the schematics show a 1µF cap. Page 28 and page 29 are also mentioning pretty much the same text, where page 28 might be an extension on page 29.
Thanks,
Falco
