PBTL operation is obtained from the EVM by paralleling outputs after the final filters. PBTL operation per the IC datasheet is obtained by paralleling IC outputs before the final filters, which requires fewer filter components. But the 1.0uF filter caps shown in the datasheet are different from the 0.68uF caps in the EVM's. Is the difference important? So far I have only dealt with EVM's but I have to submit a real design soon.
To complicate the question more: I do not need all of the output power possible from a TAS5630, so I anticipate using larger filter inductors (15uH per TAS5615 datasheet and EVM, versus 7uH per TAS5630 datasheet and EVM). In that case, would the difference in filter caps be important? I prefer to use 0.68uF WIMA caps because they are substantially smaller than 1.0uF WIMA caps.
